So far with the Cypress grep plugin we have looked at how to run tests with certain tags, how to run tests that have no tags, and how to increase the performance of the plugin when running filtered tests.
In this post, we are going to look at how to run tests multiple times to ensure that they are flake free. I have several times run into issues where we think a tests is working great only to find out if you run it a 2nd time that it fails or causes other tests to fail since Cypress without the Cypress grep plugin will only run each passing tests once.
By default, for the Cypress grep plugin when using the grep and grepTags all of the specs are executed and then each the filters are applied. This can be very wasteful, if only a few specs contain the grep in the test titles. Thus when doing the positive grep, you can pre-filter specs using the grepFilterSpecs=true parameter.
In the previous post on the Cypress Grep Plugin we installed and went through the basics of how to run just tests that have certain tags but what if you want to run all tests that do not have any tags?
One of the features that I wish Cypress had is a way to group feature tests together so that I can run all tests for the feature I am currently coding or testing without having to put them all into the same spec file. Now you can with the Cypress grep plugin.
