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 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 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/
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!
To make a long story short, I'd like to run my jest tests (using CLI) with electron instead of node.
It's relevant when using native module, because you need to build them using electron header while jest run them using plain node.
So I must either build my native modules for my app (at least in dev mode) or my tests, I can't have both to work.
In this thread they propose to use mocha, but I want to use jest, which is far more advanced and interact well with React.
Note that I don't want to mock the native module, since I write integration tests.
I opened an issue about the zmq github repo. One proposed solution is "to target your tests using ELECTRON_RUN_AS_NODE=true electron as your node runtime".
This is a very good solution, since using electron will both make the test environment closer to the execution environment and solve my specific issue with native modules.
I'd like to apply that, but I do no seem to be able to setup the jest CLI to use electron instead of node, and I have no idea where to start. Maybe I should run jest programmatically without the CLI ? But I might lose the nice test filtering features of the CLI.
Has anyone solved this already?
"ELECTRON_RUN_AS_NODE=true ./node_modules/.bin/electron ./node_modules/.bin/jest works fine
If you're on Windows, then Eric Burel's excellent discovery might need a bit of a tweak to use the environment variable, and call the right version of Jest:
cross-env ELECTRON_RUN_AS_NODE=true ./node_modules/.bin/electron ./node_modules/jest-cli/bin/jest.js
Sadly, the colouring of the text in the results is lost.
I've created a CLI using commander.js.
I've written unit tests for all my source code, but I'd like to write an integration test that uses the executable file.
How do people test CLIs? I can hack something together, but I assume there must a best practice for testing CLIs.
I ended up using an assert function in my tests.
