I am using Vitest as the testing framework for my project.
I have a directory called canRunInParallel which contains multiple test files, like A.spec.ts, B.spec.ts ..... Z.spec.ts. Since this directory contains multiple test files, and none of the tests can race condition, I want to configure Vitest to run all these tests concurrently, so that I can improve my testing time.
Can anyone help me in figuring out how to achieve the same (by most probably modifying the configuration of Vitest runner)?
This functionality is not yet supported by Vitest.
You can only run the tests in a test suite (test file) concurrently using Vitest.

I am using Vitest as my testing framework in a project.
I have multiple test files in the project, let's say A.spec.ts and B.spec.test. I am using the standard test script (vitest run --no-threads --coverage) to test my code. I want to run a certain function (to purge and clean the testing database), before and after all the test suites are run (i.e. before all the tests in A.spec.ts and B.spec.ts, and after them as well).
Is there any way to achieve the same? I read about the methods like beforeAll and afterAll, but they work in the context of a file, and thus do not help with my use case.
you should try global setup

I really love cargo and how easy it is to write unit tests.
However, it seems like it's testing functionality is fairly basic. What I'd like to be able to do is have named groups of tests somehow. What I am trying to accomplish is to have a default set of tests that execute when you run the basic cargo test. However, some of my tests take much longer to run, so I'd like to be able to move these to another group of extended tests that I can run with some command like cargo test --extended, and also the ability to be able to run all the tests at once easily. I also have a third group of tests that I have currently implemented as ignored tests so I can run them separately.
Even though all my tests are effectively unit tests, I tried to accomplish this by creating a tests directory as you would do with integration tests. However it seems that the basic cargo test command wants to run the all these tests, i.e. the normal tests that are part of my crate as well as the extended tests in the tests crate.
Does anyone know how to accomplish this or whether there is some crate that provides this functionality?
You could use a combination of feature flags and the #ignore macro as mentioned here: https://www.reddit.com/r/rust/comments/3i1nki/how_to_skip_expensive_tests_with_cargo_test/
My boss asked me to delete Non usable files in my project and asked me to delete ExampleUnitTest and ExampleInstrumentedTest What are these files used for and will it gonna be a problem if I deleted them?
A simple response is : No, there is no problem if you delete this files.
You can evaluate your app's logic using local unit tests when you need to run tests more quickly and don't need the fidelity and confidence associated with running tests on a real device. With this approach, you normally fulfill your dependency relationships using either Robolectric or a mocking framework, such as Mockito. Usually, the types of dependencies associated with your tests determine which tool you use:
If you have dependencies on the Android framework, particularly those that create complex interactions with the framework, it's better to include framework dependencies using Robolectric.
If your tests have minimal dependencies on the Android framework, or if the tests depend only on your own objects, it's fine to include mock dependencies using a mocking framework like Mockito.
Then instrumented unit tests are tests that run on physical devices and emulators. Instrumented tests provide more fidelity than local unit tests, but they run much more slowly. Therefore, we recommend using instrumented unit tests only in cases where you must test against the behavior of a real device.
I have a test suite and because it contains some expensive tests, I disable some of them for our CI. However once a day, I'd like to run the whole test suite.
The issue is that running against the same set of test files, it causes snapshot failures because when running the whole test suite it is missing some. If I generate them, then the CI fails because it complains about snapshots being removed (i.e. the one from the whole test suite that are not being checked on the CI.)
What would be the proper way to handle this with jest?
Thanks!
I have created a few coded ui tests and linked them to the test case, and they now appear as automated and you can see the dll they link to in the test case details.
Now that I want to run the tests, MTM refuses to even start the test unless a build is defined.
However: I want to run the tests against a statically installed application in the lab environment. This is an application that I manually install, and I get this application already compiled, so no need to play around building it.
So how can I take the build server out of the loop? I don't need the application built or deployed, I'm already doing that.
All I want is the tests to run on the lab environment specified against an application that is already preinstalled.
It's asking you to define the build of the test solution, assuming that it's different from your application under test. The test assembly will be deployed to the test environment after you specify it in MTM. This article may help you with the specifics.
It is asking you to create a build for your Coded UI test solution. It requires that the tests be built so that it has something to execute when you run the tests. Assuming that your tests were recorded using your statically deployed application then they will test that same application.
