How to run chromium test

[18f]

Hey, chromium have many unittest file. I have read some document, like this  Testing in Chromium - Running web tests using the content shell (googlesource.com).

But this  just include blink test. chromium all have another intersting test file. like this pending_beacon_host_unittest.cc - Chromium Code Search. The unitest.cc don't belong blink. and my question is how to run unitest like this? Any suggestion or document will be welcome. Thanks!

The hard way (but simple) is to find the BUILD.gn file that references that file. In this case the search leads you here

https://source.chromium.org/chromium/chromium/src/+/main:content/test/BUILD.gn?q=pending_beacon_host_unittest.cc%20file:BUILD.gn&ss=chromium

Then scroll up to find out what test binary it is compiled in. In this case we are lucky and we don't have to scroll up very far. Sometimes, it's hundreds of lines

https://source.chromium.org/chromium/chromium/src/+/main:content/test/BUILD.gn;l=2234;drc=fff62af2b547c25e4f1a744beb638d862fef4b63

To find that it's content_unittests. Build and run that to execute the test.

The easy way to do all of that is

$@ gn refs out/Default content/browser/renderer_host/pending_beacon_host_unittest.cc
//content/test:content_unittests

autotest.py (https://source.chromium.org/chromium/chromium/src/+/main:tools/autotest.py) is even simpler:

tools/autotest.py -C out/Default pending_beacon_host_unittest.cc

will automatically search the BUILD.gn files to find the test binary, and scan the test file itself to determine the names of the tests in it.

You can append additional test filters to target specific tests if you want to as well (sometimes there are a *lot* of tests in a single .cc file, and you really only want to run one or two of them)
