Command to run two or multiple tests

You're correct that -t will only match a test name, but -T (capital) or --test-grep will allow you to match a pattern.

If the tests you want to run are grouped in a fixture, you can also run a particular fixture with -f or a set of fixtures with -F to match a pattern (similar to -T)

You can run multiple TestCafe tests using below command, for e.g.

// Matching different search patterns
testcafe -e -u chrome testcafe/tests -T 'pattern1|pattern2|pattern3'

// Matching similar search patterns L0 and L1 using regex
testcafe -e -u chrome testcafe/tests -T 'L[01]'
