END-TO-END TESTING

Remember when you test a system for APIs you can think about the water tubes in a house? Well, I am going to use this same example for end-to-end (E2E) testing. When you carry out a test like this, it means that you are going to test it from start to finish, much like identifying if the water flowing into and out of the house is working. This testing will look at the program or application from start to finish to ensure that the whole system is working appropriately. In this case, the test will simulate real-life use and application as if the user were accessing the system.

During this process, the environment will be set up on a machine to simulate the conditions in which the user will access the program for the tests to be executed. This will be carried out by the tester to ensure that all the client requirements are met. However, once again, I want to reinforce that the tester will not just be “clicking away.” This process is carried out in a planned and systematic way to ensure that all the potential issues are identified and that all scenarios are tested accordingly. Once the tests are concluded, the results will be analyzed to identify if the software is compliant.

Although there are different ways to approach this process, one of the ways that testers can identify if the program is in accordance with the standards is by establishing metrics that will enable them to quantify the results. These metrics can include how long each test takes to be executed, if there are any overload or stability problems when the program is running, and even the success rating of the process. Because these tests are so comprehensive and complex, they might take some time to be executed and, therefore, must be planned accordingly so that no delays are incurred for the delivery of the final product.

One of the main advantages of this test is that, since it will be applied on a real-life basis, any potential bugs that might have been missed during the other test phases can be identified and corrected. It will also be important to foresee during this process any “deviations” or unexpected actions in the actions conducted by the user while they are working with the software. This will be the last step of testing prior to deploying the application to the final user, and, therefore, you should consider that it is the “final barrier” between the development and the release phase.
