Web Application Testing Best Practices

Web Application Testing Best Paractice

The rise of mobile apps and decline of desktop browsing have made it essential for enterprises to build mobile-friendly websites. Also, the enterprises must deploy skilled testers to evaluate all aspects of the website across browsers, platforms, and devices. The testers must evaluate the web application’s accessibility, functionality, performance, usability, and security to produce more accurate test results. Also, they need to explore ways to accelerate web application testing and enhance test coverage. The testers can always implement several web application testing best practices to produce accurate and reliable test results without increasing testing time.

10 Web Application Testing Best Practices Each Tester Must Know

1) Integrate Exploratory Testing with Conventional Testing Techniques

Many testers nowadays perform exploratory testing to reduce testing time and uncover more defects. The software testing approach requires testers to write and execute test cases simultaneously, while using their imagination. But testing professionals often forget the shortcomings of exploratory testing. They can easily overcome the shortcomings by integrating exploratory testing with other black-hat and white-hat software testing techniques. The integration will help them to produce more reliable test results, while reducing the testing time significantly.

2) Don’t Forget to Perform Sanity Testing

Often testers ignore sanity testing as a subset of regression testing. But sanity testing helps QA professionals to evaluate the features and functionality of the web application within a short amount of time. Also, the testers can perform sanity testing to check if the web application is working as expected despite bug fixes and code changes. Often testers find it difficult to execute the required tests due to time constraints. They can run the sanity test cases to check evaluate the health of the website within a short amount of time.

3) Test All Third-Party Applications, Plug-ins, and Extensions

Nowadays, each web application uses a variety of third-party plug-ins, extensions, and applications. These third-party resources help programmers to enhance the web application’s functionality and performance without writing additional code. But the quality of individual plug-ins, extensions, and applications differ. The testers must check if the extensions and plug-ins are fully compatible with the web application. Also, they need to identify the defects in an extension or plug-in that affects the website’s performance adversely. Likewise, the testers also need to check if the performance of the web application is being impacted by third-party applications for social media, live chat, embedded video, search, or RSS feed.

4) Decide the Best Way to Test Chatbots

Nowadays, most websites use chatbots to interact with visitors proactively through textual and auditory methods. But often testers find it difficult to test chatbots effectively. They can test the chatbots precisely to ensure that they are interacting with visitors just like customer support executives. The testing professionals must evaluate chatbots in varying testing environments. Also, they have to check if the bots are coordinating with each user proactively. However, they must automate the chatbots testing process to evaluate the software under varying conditions within a short amount of time.

5) Focus on Keeping URL String Unalterable

While performing security testing, testers often focus on the security features of the web application. They also evaluate the effectiveness of the web application in keeping in enterprise and user data secure. But the cyber criminals can manipulate the URL string to access sensitive date or redirect users to a malicious website. Some of these malicious websites are designed specifically to install malware on the user’s system or convince users to share sensitive information like credit card details. The testers must check if the URLs can be manipulated by potential hackers as part of the security testing process.

6) Emulate Potential Hackers

While evaluating a web application, testers often emulate end users to assess its user experience precisely. But the testing professionals cannot assess the security of the website accurately by emulating end users. While performing security testing, they must emulate potential hackers and cyber criminals to produce better test results. Like hackers, they must look for the path to access the web application with minimal resistance. Further, they can make the test designing and test scenario writing process more effective by thinking like a potential hacker.

7) Don’t Ignore Cross-Browser Compatibility Testing

With more and more users accessing websites on mobile devices, most enterprises nowadays explore ways to make their websites mobile friendly. Many enterprises opt for responsive web design to make their websites look good on both computers and mobile devices with a single code base. The developers build responsive websites with open technologies like HTML5, CSS3 and JavaScript. The older versions of major web browsers do not support HTML5 and CSS3 fully. Hence, the testers must perform cross-browser compatibility testing to ensure that the website is accessible on various versions of individual web browsers.

8) Perform Load Tests in Cycles

Load testing helps testers to evaluate the website’s performance under both normal and peak load conditions. The testers can further use robust test automation tools to accelerate load testing. But they must perform load tests in cycles to check how the web application performs under varying load conditions. Also, they must perform load testing incrementally and increase the use load gradually. The gradual increase in user load will make it easier for testers to identify the point where the web application crashes due to excessive user load.

9) Choose the Right Parameters for Usability Testing

While testing a website, the testers must evaluate it user interface (UI) and user experience (UX) to produce more accurate test results. Also, they must perform elaborate usability testing based on a number of key parameters. It is always important to perform usability testing based on key parameters like UI design, speed, navigability, accessibility, and content readability. At the same time, the testers must emulate all probable user actions to check the amount of time required to perform a specific action.

10) Be a Part of Development Team

The number of enterprises adopting agile methodology or DevOps has been increasing consistently. Agile methodology required enterprises to unify software development and testing activities. In addition to testing the web application throughout the software development lifecycle, the QA professionals also need to coordinate with developers, business analysts, and customer.  DevOps requires practitioners to unify software development, testing, and deployment activities. Hence, the testers must learn how to work with programmers and IT professionals as a single team.

On the whole, the testers can implement several best practices to accelerate web application testing. But they still need to decide the right testing techniques and best practices according to the requirements of individual websites. Also, the testers must keep looking for new web application testing best practices to produce more accurate and reliable test results.

Error 80070012: Unexpected error launching spoon based internet explorer

“Unexpected error launching internet explorer IELaunchURL error returned 80070012” while running Selenium Scripts in IE spoon browsers:


I was facing a very critical/weird issue(very easy after it got resolved :)) while running Selenium script in IE spoon browsers.. I was opening the Spoon browser through the Selenium standalone server in port 5555 and the server was running fine in the same port.

But while i was trying to execute the script in IE9 spoon it was throwing some error message(where the server is running) like “Unexpected error launching internet explorer IELaunchURL error returned 80070012” even after i have set all the protected mode as enabled, zoom level 100% and i was using the below code to open the IE browser in Spoon.

How Critical and Urgent is your Defect ? What is it ?

How Critical and Urgent is your Defect ?

What is it ?

We Testers often find it difficult to define Priority and Severity of a bug. The terms ‘Critical’ and ‘Urgent’ means the same as the terms ‘Severity’ and ‘Priority’ which are very much used in Bug Tracking System. The former terms are just listed under the later terms as options in the drop down, as simple 🙂

Agile: Experiences and Learning from Testing Perspective

What is agile methodology?
Agile has become the trend in the software business since the last decade. Everyone wants to go agile. So let’s have a look at what agile is, literally agile means to be able to move quickly and easily. Similarly, agile methodology as we know in software industry means iterative development and testing. It involves several phases like brainstorming, designing, development, testing and deployment in succession. All these taking place in a time span of a few weeks. Once the deployment of code (release) on live server is done we come back to the brainstorming phase for the next release and so the process continues. In simple words, agile methodology means working in short sprints and delivering a chunk of workable code at a time.

Agile Methodology can be broadly categorized into the following sub-processes:

Do we Need Testcases?

I was writing test cases meekly for one of my projects on a busy day at my office. A notion clung my mind why am I doing so. Is this necessary? Is it indispensable?

I tried getting inputs from my fellow colleagues, despite it was vague to question about such an imperative thing.  Every one answered in a similar fashion. It was about its benefits namely repeatability, re-usability, can be used for regression testing (particularly if you don’t have automated scripts), providing an audit trail of testing done (coverage), training – it can be useful for helping to new staff, can provide traceability to requirements etc. Alas, I got all the answers in favor of need as expected.

Test cases are not necessary as it doesn’t imply quality testing and moreover it does not make a good tester in isolation either. In quest of its need I drilled down more.

A Proposed Model for ETL Process and Testing

ETL refers as Extract, Transform and load. Comprehensive testing of a data warehouse at every point throughout the ETL process is becoming increasingly important as more data is being collected and used for strategic decision-making. In ETL process data is extracted from OLTP (Online transaction processing) database, transformed to match the data warehouse schema and loaded into the data warehouse database.

There are mainly three steps in ETL process.

  1. In the first step, ETL process is mapping the data between source and target database (data warehouse and data mart).
  2. The second step is to cleansing of source data in staging area.
  3. The third step is to transforming cleansed source data and then loading into target system.

Why ETL Required: As data sources change, the data warehouse will periodically updated. An ETL system consists of three consecutive functional steps: extraction, transformation and loading:

Bitmap Checkpoint in QTP

A checkpoint used as Verification and compares the actual Results from the   expected results in a test plan. If two values in a checkpoint gets matched then the checkpoint passes or else it will get fail .This enables you to identify whether your Web site or application is functioning correctly.   Checkpoints are stored in Local Object Repository.

Bitmap Checkpoint:

Bitmap Checkpoint

It is nothing but  checking  an area of a Web page or application as a bitmap. When we create a test ,then we need to specify the area that to be  checked. Here QTP captures the specified object as bitmap and inserts the checkpoint .Here it compares the selected areas of the object displayed in the application when recorded. After we select the bitmap, the image can be viewed in Bitmap checkpoint properties. These are dependent on factors like screen resolution, Operating systems and RGB settings.  So any changes to any of these factors will cause the checkpoint to fail. While capturing  if another app gets overlap  then that part of the screen is also captured.
