Web Application Testing Checklist

In today's world of constant improvement, unanimity is required to acknowledge that the internet has become one of the important parts of our daily routines.

Because most of us nowadays make decisions based on information found on the internet, having a website is no longer an option but a requirement for all types of organizations. It's the first step toward becoming and being market-relevant.

It is insufficient to simply have a website. A company is required to create an informative, accessible, and user-friendly website. To retain all of these traits, the website should be thoroughly examined, which is referred to as web testing. As you test your web applications, you should keep in mind the following template: Applicable to all types of web applications depending on the business requirements, the following checklist is a good place to start.

Test the web application using the web application testing checklist.

  • Usability Testing
  • Functionality Testing
  • Security Testing
  • Compatibility Testing
  • Database Testing
  • Performance Testing

Let's take a closer look over each and every type of testing and know what each means

Usability Testing

Usability testing is now a required component of any web-based project. It can be done out by testers like you or a small focus group that is representative of the web application's intended audience

Examine the website's navigation − On all of your website's pages, menus, buttons, and links to different pages should be clearly visible and stable.

Examine the Content − There should not be any spelling or grammatical mistakes in the content. If images are given, then they should have an "alt" text.

Usability Test Cases Examples

  • The content of a web page should be free of spelling and grammatical problems.

  • As per the specifications, all fonts should be the same.

  • The text should be properly aligned throughout.

  • All error messages must be free of spelling and grammatical problems, and the error message must correspond to the field label.

  • Every field should have a tooltip text.

  • All of the fields should be aligned properly.

  • Between field labels, columns, rows, and error messages, there should be enough space.

Database Testing

Your web application's database is a key component, and it must be fully tested. The given activities are parts of the testing process −

  • Check to see if there are any issues appearing while running queries.

  • When creating, updating, or deleting data in a database, data integrity is conserved.

  • Examine query reply timing and fine-tune them if it is necessary.

  • Your web application accurately shows test data recovered from your database.

Example Database Testing Test Cases:

  • Check the database's name: The database name should be consistent with the requirements.

  • Tables, columns, column types, and defaults should all be checked: Everything should be in accordance with the specifications.

  • Check whether the column allows for a null value.

  • Check each table's primary and foreign keys.

  • Check the Saved Procedure −

  • Check to see if the Stored mechanism is placed.

  • Check the name of the stored procedure.

  • Make sure the parameter names, types, and numbers are correct.

Compatibility Testing

Compatibility testing makes sure that your web application works satisfactorily on a variety of devices. This would include the following Browser Compatibility Test: The same website will appear differently in various browsers. You must make sure that your online application is shown appropriately across all browsers, that JavaScript, AJAX, and authentication are all functioning accurately. You can also see if your browser is compatible with mobile devices.

With each change in the Operating System, the rendering of web elements such as buttons, text fields, and so on changes. Ensure that your website is suited to a variety of operating systems, that are Windows, Linux, and Mac, as well as browsers like Firefox, Internet Explorer, and Safari.

Scenarios for Compatibility Testing:

  • Test the website in a variety of browsers (Internet Explorer, Firefox, Chrome, Safari, and Opera) to check it is working properly.

  • Make sure the HTML version you're using is compatible with the latest browsers.

  • Check that the photos are displayed accurately in various browsers.

  • Check that the fonts work in various browsers.

  • Check that the javascript code works in various browsers.

  • Animated GIFs should be tested on a variety of browsers.

Performance Testing

This will guarantee that your site functions properly under all load conditions. Activities for software testing will comprise of but are not bound to −

  • Response time of website at different network speeds

  • Test your web application under typical and maximum loads to see how it responses

  • Test your website to see where it breaks when it's subjected to higher-than-normal loads during peak hours.

  • Test how the site retrieves from a crash produced by maximum load.

  • To reduce load times, make sure optimization techniques like gzip compression, browser, and server-side cache are enabled

Scenarios for general testing:

  • To test an application's performance, stability, and scalability under various load scenarios.

  • To see if the existing architecture can handle the application's maximum user load.

  • To figure out which configuration sizing gives you the most performance.

  • To locate bottlenecks in the application and infrastructure.

  • Determine whether the new software version has a negative influence on response time.

  • To determine if a product and/or hardware can manage expected load quantities.

Security testing

For e-commerce websites that contain sensitive client information such as credit cards, security testing is essential. The given activities are parts of the testing process −

  • unauthorized access to secure pages should not be allowed during the time of testing.

  • if not having appropriate access, private files should not be downloaded.

  • After a period of not using, sessions should be automatically terminated.

  • When SSL certificates are utilized, the website should be redirected to SSL pages that are encrypted.

Examples of Security Testing Scenarios:

  • Verify that any online page containing sensitive information, such as a password, credit card numbers, or secret answers to security questions, is uploaded over HTTPS (SSL).

  • Important information, such as passwords and credit card numbers, should be displayed in an encrypted format.

  • All authentication pages, such as Registration, Forgot Password, and Change Password, have password verification requirements in place.

  • All authentication pages, such as Registration, Forgot Password, and Change Password, have password verification requirements in place.

  • Check to see whether any important information is displayed in the error messages.

Functionality testing

What is Functional Testing and How It Works?

Testing a product's features and operating behavior to confirm they meet its standards. Testing that overlooks a system's or component's internal mechanisms and focuses entirely on the outputs produced in response to specific inputs and execution conditions.

What is Functional Testing's Purpose or Goal?

Functional testing's purpose is to ensure that your product meets the functional specifications specified in your development documents.

All links on websites should be checked, as well as database connections, forms for submitting or receiving data from users on web pages, cookie testing, and so on.

Cookie Evaluation

Cookies are tiny files that are saved on the user's computer. These are primarily used to keep track of sessions, particularly login sessions. By enabling or disabling cookies in your browser's settings, you can test the application.

Before writing to the user's system, make sure the cookies are encrypted. Check for login sessions and user metrics after the session finishes if you're testing session cookies (i.e. cookies that expire after the session ends). By deleting the cookies, you can see how it affects the application's security.

Testing Databases:

In a web application, data consistency is also critical. While editing, deleting, or modifying forms, or doing other DB-related tasks, check for data integrity and errors.

Check that all database queries are correctly executed, and that data is retrieved and updated. More on database testing could be a burden on the database; we'll cover this in the section below on web load or performance testing.

Scenarios for Functional Testing:

  • Validation should be performed on all essential fields.

  • For all mandatory fields, the asterisk sign should appear.

  • For optional fields, the system should not produce an error message.

  • Verify those leap years are accurately validated and do not result in errors or miscalculations.

  • The numeric fields should not accept the alphabets during testing, and an appropriate error message should appear.

  • If negative integers are permitted in numeric fields, check for them.

  • For calculations, test division by zero should be handled effectively.

  • To verify that the data is not truncated, check the maximum length of each field.

Some Test Scenario

A few other things to think about when evaluating a website are listed below.

  • What is the server's expected load (for example, the number of hits per unit time)?

  • What level of performance is necessary for each loading scenario (for example, web server response time and database query response time)?

  • What kind of performance testing tools will be required (e.g., web load testing tools, other in-house tools that can be customized, web robot downloading tools, etc.)?

  • What is the target audience? Who is the intended audience? It'll be interesting to see what browsers they use. They will be using what kind of connection speeds. Internet-wide or intra-organizational (high connection speeds and similar browsers)?
