In this blog, I’d like to show you various strategies and tools how you can skip your test and run them conditionally. In the past, I wrote a blogpost on how you can grep your tests using module API. You might like that as well.
The easiest way to skip or filter a test is to use
.skip functions. You can use them with multiple tests in a single spec, so that you’ll run only those test that you want. This code will tun only
test #1 and
And this test will only run
These work whether you use them in GUI or CI. By the way, to avoid accidentally leaving
.only in your test, make sure you setup precommit hook that will prevent this, or simply install this nice plugin. You can also use these keywords for your
describe blocks. In that case, tests will work like this:
cypress.json you can specify which tests you want to run or skip. You can use the name of your tests or use minimatch to pick which tests should run. Let’s say you have three tests:
To just run
test1, you’d put this in your
If you use subfolders in your
integration folder, you can select all tests with the same name inside all of those folder by passing
**/test.ts. More importantly, if you use a naming convention for your smoke tests, like
test.smoke.ts, you can filter these by passing
*.smoke.ts to your
testFiles. So for example this configuration will run just our
All these principles apply to skipping tests as well. For ignoring your test files, use
ignoreTestFiles. You can also pass arrays these attributes. These can contain either test name or minimatch, so you can do stuff like:
If you want to add more complex conditions to your tests, you can use spec configuration. For example, you can configure your test to run only in a certain browser.
This test will only run when the set viewport is larger than 350 pixels.
There’s a really nice plugin that enables you to skip your tests based on various conditions. It makes it easier to run certain tests only on Mac or only on Windows, as well as skip them using these conditions. It looks something like this:
There are more cool examples on readme page, make sure you check them out. What’s even cooler, you can set any condition you like with this plugin, so our mobile-only example from above would be written like this:
Similarly to our
cypress.json configuration, we can pass CLI arguments to run only those tests we want. To run only smoke tests we’ll run:
To run all tests except the smoke ones, we’ll run a command like this:
There are quite a lot options you can use out there. I described one of them in my blog. With Module API, there’s really nothing stopping you from organizing your test suite in various different ways. There’s also an option for grepping all of your tests via plugin. Whichever you choose!
