Web App Testing: To Launch A Bug-Free Web App

Just having a web application is not enough for your business to thrive. After all, you should launch a secure and user-friendly web app that is useful for your business and customers. So you must ensure that you are launching a bug-free web app.

But is it possible to launch an error-free web app without conducting proper web app testing? Certainly not. That’s why thorough web app testing is important before release.

Testing web applications is not only important to ensure the quality of this vital tool. It can also save you from the extra cost of bug-fixing, which keeps varying with time.

So, continue reading this article for a complete understanding of web app testing.

What is web app testing?

It is a method of verifying a web application or website to identify bugs. This stage is crucial for removing all the errors before making them accessible to the users. This process includes verifying the functionality, security, usability, and also performance of the application.

A thorough web app testing process includes the following stages:

  • Usability testing
  • Functionality testing
  • Interface testing
  • Compatibility testing
  • Security testing
  • Performance testing

Web App Testing: Step by Step Process

Each stage of developing an intuitive web application is vital. Quality checking is an unavoidable step. That’s why every leading web app development service company in India, like Futuristic Bug, prefers to conduct a thorough testing process. To know all the stages of testing a web app, check the following points.

Functionality testing:

This is regarded as the first step of conducting the testing of your web application. After all, it ensures that the web app is functionally correct or not. During this stage of testing the experts check the database connection. Besides, it includes checking all the links in the web pages, cookies, etc. You need to speed up the whole app-building process. That’s why you need to stay updated about the functionality of your web app.

After receiving the result from this stage, you must compare it with the desired results. Moreover, you cannot complete this once as you need to verify this with various other data inputs. But how would you know if you have reached the expected result? When you will observe the same level of accuracy each time. Above all, to remove most of the errors, you must conduct functionality tests frequently.

This stage includes the following activities:

  • Testing if the outgoing links, internal links, anchor links, and mail-to links are working properly. Besides, it also includes identifying any broken links on the web app.
  • Verifying if the forms are working properly. It includes scripting checks on the forms.
  • Cookie testing is another crucial part of this stage.
  • Checking HTML and CSS for ensuring that the search engines can crawl the site seamlessly.
  • The stage of functionality also includes the test of end to end workflow of your business.

Usability testing:

The second stage of testing your web app is its usability testing. It is mainly a combination of the entire user experience testing with functionality testing. It is certainly not typical user acceptance testing.

To conduct the usability test, you can count on external testers. However, the developers can also conduct the test internally. Various external app testers are available, and Apple’s TestFlight is a famous name.

The following actions are taken during this stage:

  • It involves testing if your website is easy to navigate. So you must check if all the menus, buttons, or links on the pages of your site are visible. Most importantly, ensure consistency.
  • Testing the content is another important step. Therefore, ensure that the content is free from grammatical spelling mistakes. Moreover, it has to be legible.
  • The usage of ‘alt’ text is a must if there is any image on the site.

Interface testing:

The verification of the seamless interaction between the server of the web app and the web server is important. Through interface testing, you can conduct it properly before releasing the web application. Besides, find out if error messages played through this testing. Following are the areas that you must verify through this phase:

  • Testing around the application is necessary to see if the administrator can see the error and not the end user.
  • Verify the web server area to check if the web server is managing every application request without any trouble.
  • Verification of the database server helps to check if expected results are received from all the queries sent.

Compatibility testing:

Through this phase, you will be able to know if your web app is compatible with all types of devices. Moreover, it is also important to verify the compatibility of your application with mobile browsers. Therefore, the developers must ensure that the web app is running across all mobile browsers.

Web app development services providers in India prefer conducting compatibility tests with various operating systems. This is crucial because different operating systems display certain web app elements in various ways. So, your app should work well for various types of operating systems like Windows, Mac, Linux, etc.

Performance testing:

You need to know how your web app performs at various internet speeds. This is why performance testing is necessary before releasing the web app.

Experts suggest conducting the testing on a basic level. You can conduct this test with various tools already available in the market.

Keep in mind the points below to conduct performance testing:

  • Checking the response times at different connection speeds.
  • Load testing is a must to understand the behaviour of the web app under normal and peak loads.
  • Understanding the breakpoint speed testing is important.
  • To identify if any crush occurs because of peak loads.

Security testing:

Whether your web app is secured or not is also important to verify. That’s why security testing is another crucial quality checking phase. Moreover, it also helps you to identify the weak points of the app and fix the issues.

Following are some important steps to take through such phases:

  • To understand the security goals and strategize accordingly
  • Identifying the reasons for the vulnerabilities of the web app
  • Understanding the potential threats
  • Strategizing a proper test plan
  • It is mandatory to build the security case documents
  • Rectifying all the detected issues and also testing again
  • Creation of an elaborate report on the security testing

Some useful tools:

Conducting web app testing will not seem a great deal when you are using the following tools.

  • Bitbar: To verify if you are providing the best web and mobile app experience to your users Bitbar is helpful.
  • Load Ninja: To load test your web app with real browsers, you can count on this tool.
  • Lambda test: To check if all the elements of your web app are visible across all the devices, this tool will help you.
