[SOLVED] How to run all tests, including system tests, at once in Rails 6?

How to run all tests, including system tests, at once in Rails 6?

To run tests in Rails 5+, I'd do two separate commands:

$ rails test
# Running:
........    
$ rails test:system
# Running:
........

How can I run both sets of tests from a single command line request?

Solution

To run all tests, you can list them all:

$ rails test:system test:models test:mailers ....

And you'll get the correct summarized totals:

Finished in 15.824006s, 1.8327 runs/s, 4.2973 assertions/s.
30 runs, 69 assertions, 0 failures, 0 errors, 0 skips

The shortcut is to do:

$ rails test:system test
Finished in 14.427353s, 2.0794 runs/s, 4.7826 assertions/s.
30 runs, 69 assertions, 0 failures, 0 errors, 0 skips

Which will do all of your tests since "test" includes all tests, except 'test:system'. One caveat is that if you list 'test' first, it won't run your system tests.

So, this will only run 'test', and not 'test:system'

$ rails test test:system
Finished in 0.736070s, 13.5857 runs/s, 23.0956 assertions/s.
10 runs, 17 assertions, 0 failures, 0 errors, 0 skips
