Triple Your App Downloads By Developing Minimum Viable Product!

You have got an amazing app idea! That’s great! Now, all you need to do is get it turned into a splendid application and cherishes huge user retention rate and sales revenue… right? Well, this is the ultimate stuff that every startup or entrepreneur wants from its app. So, what happens if you have spent years in the development of an amazing application and when the final product is released and there are no conversions? You would simply end up with the loss of time, money and your valuable resources.

As we know, there are lots of expectations tied up with a newly launched product. It includes adding to the brand value, gaining a competitive edge, securing your investments and much more. So, an unexpected output due to lack of practical knowledge of users need could risk up your developer’s efforts and the investment done. What’s the way out there? This is where the existence of Minimum Viable Product is highly significant to avoid such unnecessary risks in Mobile App Development.

MVP – The Right Choice

To most of us, Minimum Viable Product is just an acronym of MVP. Well, MVP stands more of concept rather than a technique. An MVP mobile app is a product with basic features that forms its base. Developing MVP for your product is pretty simple. Decide exactly what your USP is, represent it clearly in front of your customers and see their responses. Despite developing a company first product that may or may not a success, releasing MVP at an early stage gives you plenty of time to accumulate the data and gauge intended customer interest areas.

There are innumerable companies like GlamSquad, Amazon, Taproot+ and much more that have made use of MVP.


Let’s assume that you want to make a photo editing app. The first thing that any mobile application development company would leverage you is a basic app that allows you to add 5 filters to an image followed by adding a frame. Once the basic concept is approached and liked by your targeted set of audience, you will strategize with phase 2 development.

When app developers have earned enough profit from phase 1, they will provide you with some more advanced features like adding more filters, frames, and accessories like hairband, bow, tie, sandals and more. Now phase 2 is cleared and another round of profit is credited in developer’s account, it will soon launch phase 3 where collage maker and sharing would be an addition to the existing app.

This is how MVP actually works. To have a better understanding of MVP approach for mobile app development, let’s find out how we can use it.

How MVP Influence App Developers And Mobile App

  1. Evaluating Market Demand:

No one can predict the demands of new applications. So, in order to evaluate whether you app idea would be adopted by your audience or not, it is recommendable to create a video or teaser page and gauge its subscription list. High-blown up the list would clearly indicate that large mass of people is highly interested in your app idea. Social media is one of the best tools to evaluate market demands in most cost effective way.

2. Identify App Potentials:

Though an MVP of a particular app may not seem to be the outstanding versions, still it can have the potentials of turning it into best one. If the MVP version of your app is liked by your audiences, app developers are likely to expand and improve the app by adding more features and functions and improve or re-design complete app in order to save your investments in the app. Thus, the final product is expected to reach the desired level of success in the best possible way.

3. Helps To Achieve Customization:

Though your app final version may have gain success for one set of audience but it may result in losing another part of the audience. With minimum viable version, app developers can involve all flavors of users and create a tailored version that would undoubtedly expand your app reach.

4. Eliminating Risks:

Every new mobile app developed has a risk of being compared to the best-featured app of its niche. Another set of risk associated with the mobile application is to stand strong in terms of ideal performance. It may run well at developers end but may crash or report bugs in users smartphone and there would be no room to fix those bugs. Development of an app MVP version eliminates those risks and leads developers towards the development of a top-notch application.

Real-time data collected from users are far better than the data of pre-development research. So, if you want to develop the best mobile app for your business, ask you app development company to acknowledge you with MVP version of your app to map success in an app store.

Why Software Testing is necessary

“Quality is never an accident; it is always the result of intelligent effort.”


We all know that IT firms commit a substantial amount of Human and Machine resources for the development of various software products according to requirements specified by Clients. Software Testing is Obligatory because Every human being makes mistakes. Many of these mistakes are minor, but some of them are expensive or dangerous.

In the Digital era, we all have had an experience with software or Application that didn’t work as expected. Software that does not work can have a large impact on A Brand or Company.


  • Financial Loss – Financial loss covers losing users right through to Financial penalties for non-compliance to legal requirements
  • Waste of Time – This impacts more in our busy life, Because if transactions taking a long time to process and didn’t get the right outcome. Also, can include staff not being able to work due to a fault or failure
  • Damage to business reputation – If a company’s product or Application is unable to provide service to their customers due to software problems then the customers will lose confidence or faith from the organization and probably Swift their business elsewhere or will go for the other competitors either.
  • Injury or death – It might sound dramatic but some safety-critical systems or Robotic surgery could result in injuries or deaths if they don’t work properly.

The importance of software testing:

  • Software testing is necessary to specify bugs developed in SDLC’s Development Phase.
  • To prevents the user from facing the problems of usability and gain the confidence about the reliability of the software or application.
  • It’s really required to ensure, that an application shouldn’t drag into any defects because it can be very expensive in the future or in the later stages of the development.

At Kaira Software Pvt. Ltd., all our resources are ISTQB certified, meaning they are tested for their software testing skills.

Importance of Unit Testing

“Every large system that works started as a small system that worked”

What is unit testing?

It is a crucial part of Software Testing Life Cycle to test and inspect the individual or stand alone testable code fragments, also called Units of an application for their enduring and immediate effects.

“Unit testing is the method of verifying the smallest piece of testable code against its requirement.” Unit tests are basically written and executed by software developers to make sure that code meets its design and requirements and behaves as expected.

The importance of Unit Test:

 Unit testing is used to prepare strong software units that help to keep code and eliminate the issues in code units. Unit testing is an integral part of the agile software development process.

Unit testing includes bugs in the implementation of programmer and missing parts or flaws of the specification for the unit. The cost of finding a bug before actual coding begins or when the code is first written is greatly lower than the cost of detecting, identifying, and correcting the bug in the later stage of Software development cycle.

Unit testing permits the developer to refactor code or upgrade system libraries at a later date and make sure the module still works correctly.

Advantages of Unit Testing:

  • Decrease error in fresh developed features or reduces bugs when changing the already existing functionality.
  • Reduces Testing cost as bugs are inspected in very early phase.
  • Improves design and allows better reusable of code.
  • Unit Tests, when integrated with build gives the quality of the build as well.
  • Debugging is easy. When a test fails, only the latest changes need to be debugged. 

“Quality is not an act, it is a habit.”

At Kaira Software Pvt. Ltd. we are advanced skill-set holders in software testing, essentially mastering unit testing with the wide array of tools and technologies like PhpUnit, Mockito, JUnit etc.

New Use For Control Adapters 1

Control adapters were much discussed when they came out with 2.0 but nobody seems to have done anything beyond what was given at .
We found a useful application that solved another problem and I feel there may be more uses we can put it to. Here is the first one we discovered.

The problem
Like most applications, we needed tabs.  JS tabs without iframes would mean keeping all the data on same page. That would have made it complex and data intensive JS tabs would also require a conscious effort so that they degrade gracefully. Another issue was to implement security feature where certain tabs would not be available based on roles of the user.  Maintaining tab selection on postback was another problem.
Iframes are loose and require much more effort to stop them from ruining user experience in some cases with large number of fields and several grids and buttons on a single tab in addition to having some of the problems described above.
Finally we decided that it was best to have separate pages and not use js/iframe based tabs for our purpose.

The Solution:

For a while we used a solution where we created a ul and hide or disabled items as needed.
Later when we were trying to implement a menu adapter for office bar/Ribbon, I realized that it can also be used for generating the tabs as we need.
It would

  1. Make the solution generic.
  2. Integrate with regular .Net security infrastructure
  3. Remove what was essentially a navigation control logic from UI.
The solution was simple enough. We just needed to render appropriate set of ul and li and style them properly.

private void BuildTab(MenuItemCollection TabItem, HtmlTextWriter Writer,string MenuMode)
Writer.Write(“<ul class=’tabsubnav’ id=’ulsubnav’>”);
      int i = 0;
      if (TabItem.Count > 0)
            foreach(MenuItem item in TabItem)
                  string classval = “Unselected”;
                  if (MenuMode== “Add” && i != 0)
                        item.Enabled = false;
                        classval = “selected”;
                  if (HttpContext.Current.Request.
QueryString.Count > 0)
                      item.NavigateUrl += “?” +
                      item.Enabled = true;
                  Writer.Write(“<li id=’tabBasicInfo’>”);
                  if (item.Enabled == true)
Writer.Write(“<a href=” + item.NavigateUrl +
” class='” + classval +“‘><b><span>” +
item.Text + “</span></b></a>”);
                        classval = “disabled”;
                        item.NavigateUrl = “javascript:void(0)”;
                        Writer.Write(“<a href=” + item.NavigateUrl
+ ” class='” + classval + “‘><b><span>” +
item.Text + “</span></b></a>”);

About done.

As soon as this adapter was added to the browser file, it screwed up the Ribbon. Asp.Net Development does not allow to use multiple adapter for the same control for a given browser configuration or to choose adapter on the fly. We were already using menu adapter for the Ribbon. The solution was simply to inherit and create a new class from the menu.

class Tab : Menu

No additional code was needed.
Sitemap configuration took care of the security aspect of tabs.


   <siteMapNodeurl=~/School.aspxtitle=School roles=Access_School />
   <siteMapNodeurl=~/Locations.aspxtitle=Locationroles=Access_Location />
siteMapNodeurl=~/Grade.aspxtitle=Graderoles=Access_Grade />
siteMapNodeurl=~/Room.aspxtitle=Roomroles=Access_Room” />

The top level node is just to group the children and is not displayed. Thus we can have multiple tab sets configured in a single sitemap file.


Extension Method

Its a very frequent requirement that we have to enable/disable or hide a control based on some business logic. In one particular case, it had to be configurable by administrator as part of security and general administrative control of the site. This implied that it had to work with all the controls on the page with which user can interact and even some labels.
The controls had to be disabled according to configuration but we found out that not all webcontrols can be disabled. Surprisingly a label can be enabled and a hidden field has a visible property. It was decided that those which could not be disabled had to be made invisible.
I needed a way to disable or hide (depending on what was allowed) controls based on a condition. While this could have been as easily done in a loop with an if else block, this seems much easier to read and write. Fortunately Disable property is not used by Web Controls.


    public static void Disable(this Control c)
        Type t = c.GetType();
        PropertyInfo p = t.GetProperty(“Enabled”);
        if (p == null)
            PropertyInfo p1 = t.GetProperty(“Visible”);
            p1.SetValue(c, false, null);
            p.SetValue(c, false, null);

Label.Disable() would disable the label and
HiddenField.Disable() would make it invisible!!.

Generic testcases for selenium 1 The extension methods

Selenium is a great tool to automate UI testing but the code it generates is difficult to read and definitely not easy to maintain. The conclusion was that it was just a good code sample. Moreover, there was a huge scope of not writing code for many of the routine checks like javascript validation of data entered by user and messages.

Most selenium test cases would constitute of filling up form fields , click a button and check for error messages or their absence. Since selenium depends on strings selectors for identifying and manipulating controls, the idea was to have selectors for all sorts of form fields and populate them with random values. This would constitute the laziest testing technique but effective for checking for 500 status code or page crashes caused by not handling empty fields, not checking for data types and lengths. Taking screenshots will help notice layout issues quickly as well.

But before we start, we need to add a couple of methods to make our life easier. Selenium has a ready method GetAllFields() for getting all form inputs but it skips the select and textarea for some reason.Moreover, it does not help us to get specific controls like checkboxes to manipulate.For example checkbox can be checked using Check() and Write() is used to add text to the textboxes. This complicates the code a bit more.
To make it easier and more natural to code, we added extension methods to get each type of control.

private static string[] GetControls(ISelenium selenium, string strXPathLocator){
int cntControl = Convert.ToInt32(selenium.GetXpathCount (strXPathLocator));
string[] strControls = new string[cntControl];

     if (cntControl > 0){
for (int i = 1; i <= cntControl; i++){
strControls[i – 1] = selenium.GetAttribute(strXPathLocator + “[“ + i + “]@id”);

      return strControls;


The above method uses selenium’s general method of getting elements using XPath. It takes an instance of selenium and the XPath expression as parameter. It is private so that public methods can pass the necessary expression and allowing the test case writer to forget about Xpath. It is also in line with the GetAllFields() method provided by selenium. Unfortunately, there is no other way to get the string array of control ids yet.

Next we add a method to get specific types of inputs/controls.

public static string[] GetAllCheckBoxes(this ISelenium selenium){

  return GetControls(selenium, “//input[@type=’checkbox’]”);           


The above method is specific for the checkboxes. There will be similar ones for radiobuttons, textarea and password fields. There are a few more extensions that were added for the sake of convenience. You can download SeleniumExtender.cs for all of them.

With these extensions, we are ready to go to the next step of actually writing our testcase. This is the subject of the next post.

Using KO Validation Only If Effectively

Knockout is a JavaScript library that helps you to create rich, responsive display and editor user interfaces with a clean underlying data model. Any time you have sections of UI that update dynamically (e.g., changing depending on the user’s actions or when an external data source changes), KO can help you implement it more simply and maintainably.

It also has a validation library that has built-in methods for validating user input.

Let’s say you want to validate an observable only if a certain condition is satisfied.  We have an onlyIf property for that in ko.validation plugin.



        required: {

            message: “Value is required”,

            onlyIf: function () { return (self.Observable2() === false); }



Now, the condition may or may not depend on the same class’ property.  The key thing is it must be accessible from the extend method. Let’s assume we have the following ViewModel.


var ViewModel = function() {

    var self = this; 

    self.UserModel = {

        Email : ko.observable(),

        Password: ko.observable(),

        ChooseToRecieveMessages: ko.observable(),

        Phone: ko.observable()




Now we want Phone to be required only if ChooseToRecieveMessages is set to true. We cannot extend Phone in the UserModel directly as the declaration of ViewModel is not yet complete. The browser will throw an undefined javascript error. If UserModel was a function definition, then it is a different thing, but in this case, it’s not.

So we implement our code as follows.


$(document).ready(function() {

    var vm = new ViewModel();


       required: {

           message: “Phone is required”,

           onlyIf: function() {

               return (vm.UserModel.ChooseToRecieveMessages() == true);








We extend the observable just before applying bindings.

This technique will ensure that our ViewModel is declared before we use its properties. It will also be very helpful if we have more than one ViewModel and onlyIf depends on properties from both ViewModels.

Capture Webcame Images using Javascript + Flash For browsers

Here we are going to describe HOW we can use device cameras for taking picture using Java-scripts w/ flash. There are many third party library are available which can make this very easy. Examples a.) jQuery webcam plugin b.) JPEGCam etc.

We will use jQery webcam plugin here for capturing webcam images. Note: This plugin use flash so this examples works only with flash supporting device browser. For jQuery webcam plugin in use you have to first download webcam.js which you can get from here.

Configuration for jQuery webcam is very simple. You will have just add few line of code to make capturing enable on single click.


<div id=”webcam”></div>     /*add html element on your page*/

You have done with html configuration.

STEP 2:  JavaScript Configuration

width: 320,    /*width of your flash movie, you can adjust this as per your need*/
height: 240,   /*height of your flash movie, you can adjust this as per your need*/
