Testing is the utmost important phase of the Software Development Life Cycle (SDLC). Once the software is ready, the development team passes on the software to the Quality Assurance or testing team to perform the tests. A tester can take assistance from software developers who have all the technical knowledge of the system under test.
STLC (Software Testing Life Cycle) is a systematic approach to the multiple activities in the testing process that lead to a certified quality software product. It consists of
- Software requirements analysis
- Test planning
- Test case development
- Test environment setup
- Test Execution
- Test Closure.
5Data Inc is a world-class Performance Testing Company that tests client-server, web, distributed, mobile, cloud databases, and high-volume transaction systems.
Without further ado, let’s jump into the topic of importance.
End-to-End Testing Methodology
As the name suggests, end-to-end testing is the process that involves complete testing of an application workflow from start to finish. Interdependent and external modules are also tested for integration with the software, and these dependencies include web services and third-party connections. In the end, it ascertains a robust product that works as expected.
A prerequisite to the testing is an appropriate test plan that considerably reduces the number of bugs while testing the product. Test cases must be written keeping in mind real-world scenarios. Test automation is done where manual testing can be hectic and tedious. It is done to save time where repetitive testing of test scenarios has to be done. After completion of testing, the test environment can be restored to its original state by refreshing the test data.
At 5Data Inc, we have the best team providing functional testing services using the top automated functional testing tools like Selenium. It is a performance testing company providing performance and security testing in non-functional testing services. Our expert testers are ready to assist you in analyzing and finding the right testing methodology for your application requirements.
An Example of E2E testing
A good end-to-end testing procedure replicates real-world scenarios for validating the system for integration testing and data integrity. End-to-end testing ensures that the software works accurately across the integrated systems. Formulating your end-to-end test strategy is a good practice so that testing is executed sequentially from the end user perspective.
End-to-end testing can be executed from simple mailing systems to more complex Element Management Systems for mobile communication. A simple example of an end-to-end testing system might be a mail application like Gmail, Microsoft Outlook, or Rediff Mail. The steps to test the application might include the following:
- Go to the login page.
- Enter the user credentials.
- Submit the login page.
- Inbox access.
- Compose a mail.
- Send the mail to the test recipient.
- Log out of your mail account.

Most Common Mistakes Of E2E Testing
Test automation may not be the solution always.
The complexity of E2E testing involves testing across multiple applications and components. Test automation can be the most cost-effective solution to improve testing agility and better test coverage. Test automation tools can give accurate results and help detect bugs at the early stages of development.
While test automation can be very powerful with repetitive tests, it is only possible to partially depend on test automation code where product exploration is required. Exploratory testing can help to find the fallacies in the product effectively by keenly exploring the different components of the product.
Flaky tests
A flaky test’s outcome is usually undetermined because it may pass or fail for the same code and tests. These tests are hard to reproduce, making them difficult to debug. Flaky tests often depend on the outcome of other processes and can slow down the entire code pipeline. They usually originate from problems like synchronization issues and test order dependency. So, it’s better to identify and isolate the flaky tests before running them. There are various practices and tools available to deal with flaky tests. A tester should spend less time maintaining these flaky tests and concentrate on improving the quality of the product.
Maintenance of test code and test data
Test maintenance is difficult in E2E tests, especially when the system under test gets updated quite often. The tests need to stay updated with the changes in code and other application components, including integration and frameworks. The process of repairing the tests whenever there is a change is known as Test Maintenance. Staying aware of the changes to the system under test is the most crucial part of Test Maintenance. Similarly, test data has to be maintained and managed for multiple environments, and it should be externalized so it can be changed easily for further maintenance.
Lack of application knowledge by the testers
It’s a common observation that the testers need help understanding the system under test. These issues will reflect selecting appropriate tools to use at the beginning of testing. It’s important to know how the application works before testing it. A discussion with the developers can help to understand the application better and ensure the use of appropriate tools to test the application.
Absence of communication among teams
Failure of communication among teams can hinder the progress of testing the application and result in a poor-quality product that is not expected. All the teams should have regular sync-ups to streamline testing the application. It’s a challenging task but needs attention.
