Why is e2e testing hard?

Difficult to design tests Because end-to-end tests simulate the real-world behavior of users, there are many components to consider while designing these tests. For example, you can run a web application on many browsers, and each browser has different specifications.

What are the problems with E2E testing?

Cons of E2E Testing

Can be flaky: E2E tests can be flaky, meaning that they may fail even though the software application is working as intended. This can be due to a variety of factors, such as network connectivity issues or changes to the software application's environment.

Are end-to-end tests worth it?

I have had mixed experience with e2e testing in the past: challenging to maintain with a lot of moving parts, sometimes flakey, challenging to coordinate between repos moving at different speeds. But, when it's working, it gives a lot of confidence when you have your most important use cases covered.

Why not to automate end-to-end testing?

One of the major drawbacks to creating automated E2E tests in this fashion is the amount of code that we need to create to implement our features. In many cases, the people most interested in E2E tests are not developers (i.e., those with knowledge of or interest in code).

Who should write E2E tests?

Depends on the team composition. If your team has a dedicated AQA or SDET then it's this person job. If you don't have a dedicated person and you want have E2E tests, then it's job of FE Engineer. So front-end developer should have necessary cypress (or alternative) experience.

Writing e2e tests isn’t hard, so do it

Is automation testing dead?

Automation testing provides swift solutions and high accuracy by employing tools to execute more tests at the same time. Despite automation being time and cost-effective, the part of doing QA without having automation involved in it is still a very much necessary approach.

How does Google do end to end testing?

End-to-end testing happens in two stages: Sandbox testing and Soft-launched Production testing. Sandbox testing: Run through a series of test cases against your sandbox inventory using the sandbox frontend.

How do I learn end to end testing?

Should end to end tests be mocked?

If you still want to test the user interface from the browser, then you can mock the APIs' responses, but still not being E2E testing. In case you want to perform an end-to-end testing, then you shouldn't mock any database or API call. The exception here is a third-party API that is not under your control.

Is E2E testing the same as UAT?

UAT is conducted by end users or their representatives. E2E testing is usually performed by testers and developers. UAT tests functionality that end users will interact with directly. E2E tests the system as a whole, including components end users do not see.

What is the difference between E2E testing and regression testing?

However, they are two different types of tests that serve different purposes. End-to-end testing tests the system, whereas regression testing tests specific parts of the code. In general, end-to-end testing focuses on the system's functionality, while regression testing prioritizes the system's stability.

Should end to end tests be independent?

Tests shouldn't depend on each other

However, if test 2 fails and you are still on page A at the end of the test, now test 3 will fail as well because you are not even on page B. In this case, test 3 can only pass if test 2 passes. You've basically created a waterfall of failing tests.

Is e2e testing black box?

You should read about basics of testing like types of testing-black box, whitebox, grey box. Black box testing is testing the application without going into code. End to end testing is a type of black box testing in which we test application from a complete scenario point of view.

Is selenium end-to-end testing?

It is an end-to-end testing where in testing environment is similar to the production environment. Here, we navigate through all the features of the software and test if the end business / end feature works. We just test the end feature and don't check for data flow or do functional testing and all.

How can I speed up my end-to-end test?

Simultaneously run your tests

If you have dozens of end-to-end tests, each of which takes a substantial amount of time to perform, your whole test run may stall your team's work as they await automated test results. Check to see if your choice testing tool allows you to run your tests concurrently or in parallel.

What is an example of E2E?

Now that we understand what is E2E testing, and its pros and cons, let's understand with an E2E testing example. Scenario: Customer purchases a product from the website, pays for it, and receives a confirmation email. Objective: Verify that the entire purchasing process functions as expected.

What is another name for end to end testing?

End to End Testing is usually executed after functional and System Testing. It uses actual production like data and test environment to simulate real-time settings. E2E Testing is also called Chain Testing.

Why is QA dying?

Automation: A Game Changer, but Not the Endgame

Tools like Selenium and JUnit have facilitated the seamless integration of testing into the development workflow. This shift towards automation has led some to prematurely declare the death of traditional QA roles.

Will AI replace testers?

Software testing is not likely to become obsolete due to automation and AI. Instead, automation and AI are transforming the field of software testing, making it more efficient and effective. These technologies can enhance test coverage, improve accuracy, and enhance maintainability in software testing processes.

Is manual testing dying?

However, that doesn't mean that manual testing is “dead” or even “dying,” as many believe. On the contrary, manual testing is as essential as ever for delivering high-quality products, even with today's modern software development processes.

Should developers or QA write e2e tests?

There are a few reasons that makes QA potentially better at writing end to end tests. In-short, QA are just great at testing, probably much better than most developers: They specialise at testing. They are better at prioritizing tests because they understand which use cases are important and which are not.

How to write e2e test cases?

Why Java experts avoid mocks?

“Avoid heavy mocking. This allows you to meet the promise to refactoring. You will refactor your code and your tests won't break.” “Mocks are useful when a resource is expensive to create, but the problem with mock objects essentially is that people have used them to isolate classes.

Why use fakes instead of mocks?

Fakes are generally used to improve performance by avoiding external calls. Mocks are used to verify the behavior of our code. Stubs are used to provide data that our code needs to run. We should use the simplest test double that will get the job done.
