There are two types of end-to-end tests:
1. Horizontal Testing: Here, the tester checks a specific layer or component to see if it works reliably across different parts of the software.
For example, horizontal testing in a messaging app ensures that sending messages works smoothly on any device.
2. Vertical Testing: This guarantees that a particular function works consistently across all layers of the software, from the UI to the server and data set.
In a messaging application situation, vertical testing confirms that the whole course of sending messages works accurately. It verifies each step, from typing a message to the server handling it to the beneficiary receiving it.
Testing team uses these four indicators for assessing the progress of end-to-end tests.
1. Current Status of Test Case Preparation: You can follow this using a graph that shows the number of ready test cases compared with the complete number you initially planned.
2. Progress on Weekly Testing: This measurement assists you with tracking the progress and details of your tests week by week. It is ideal to monitor the percentage of tests you have finished and the number of passed or failed.
3. Status of Defects and Details: Tracking these measurements week after week is crucial. This data point shows the percentage of defects that have been opened and shut. It also segregated the insight by severity and business need.
4. Test Environment Availability: In this circumstance, you will monitor two significant measurements:
The planned time for running tests in a specific environment.
The genuine time spent executing end-to-end tests in those conditions.
For example, you will track each environment’s total uptime and the scheduled daily testing hours.
This type of evaluation includes testing the app completely in the testing environment. It should mimic situations that simulate real-world usage. Here are the key parameters to consider in end to end testing.
1. User Actions: Simulate real user actions such as logging in. It also checks other actions like navigating the application and carrying out transactions.
2. Data Integrity: Ensures precise and safe data transfer between various components. Such a transmission needs to happen without any loss or corruption of the secure data.
3. Performance: Here, the team measures response times and overall framework performance under varying scenarios.
4. Security: The tester checks the security of the app. They need to confirm that it shields data and assets against breaches and hack attempts.
5. Usability: Assess the UI and experience methodically. This assures the tester that it is intuitive and easy to understand.
There are different uses for end to end testing. For example, consider software for booking flight tickets.
In this instance, the tester will verify that the application runs smoothly as follows:
1. You will start by clicking on the app link. After that, you will be able to log in successfully using a genuine user ID and password.
2. At this point, you can start the booking phase. You will provide details like the travel dates and the location. Select your desired class and mode of transportation as well.
3. After that, choose the additional options and let the app know about the number of tickets you require. After that, you can use your chosen payment method to complete the purchase.
4. Completing the process will result in a printable ticket being displayed on the screen. Further, an automated copy ought to arrive on your email.
If there is any problem in any part of the app, then you won’t be able to carry out these steps. As a result, you will not be able to get the tickets as mentioned in step#4 above. This issue will be discovered thanks to E2E testing. In such a case, the developers need to check which part is leading to the product’s failure. This will help them identify the root cause and fix the issue.
Compelling end to end testing practices help in delivering a reliable application to the end user. These practices work toward accomplishing smooth testing cycles and ensuring that the end product meets quality guidelines.
Here are the best practices for E2E testing:
You need to pay attention to critical user flows and scenarios that mimic real-world usage. Here, you need to focus on testing the most important features and common user journeys. It is a smart move to use a stable test environment. It will closely resemble production and include all integrated systems and dependencies.
Next, you can automate E2E tests where possible. Doing so will tremendously improve efficiency and enable frequent execution. However, you should be careful to balance automation with manual testing. This is especially true for complex scenarios or subjective evaluations. It is better to use robust, maintainable test frameworks. Plus, the team needs to follow good coding practices in test scripts.
Also, make sure to incorporate proper test data management. This step will help ensure consistent and reliable results. Do factor in data setup and teardown processes to maintain test independence. Regularly review and update E2E tests. When you do this step, you can align with evolving application features and user behaviors.
Finally, it is crucial to integrate E2E testing into your CI/CD pipeline for early detection of issues. Also, you need to track test execution times and optimize when necessary. This step will help prevent bottlenecks in the development process.
