How do we run a single test using Google bazel

Question

For running all the tests under a target I use the command line command

bazel test //src/code_path:target_name

What should be additional parameters to run a test single_test from the above target?

On Googletest with the following setup:

TEST(TestSuite, test1)
TEST(TestSuite, test2)

you can isolate test1 using

bazel test --test_arg=--gtest_filter=TestSuite.test $TEST_TARGET_PATH

should that be `--test_arg=--gtest_filter=TestSuite.test1`? – netskink Jun 03 '22 at 20:12

For the following googletest test:

TEST(glog, log) {
  LOG(INFO) << "an INFO log message";
  VLOG(1) << "a vlog(1) message";
}

--test_filter=glog.log can be used to pick it.

You'll want to use --test_filter:

The specific format of the value to the flag depends on the test runner.

An example would help a lot. – Ernesto Cejas Nov 09 '20 at 14:45
The value to use with the flag depends on the test runner. So without more information, there's no example to give. – ahumesky Nov 18 '20 at 18:29

To give a specific example for the default C++ testrunner (not the general "depends on which test runner you use"):

For a test:

TEST_F(HiMomFixture, testCall)
{
  EXPECT_EQ(..)
}

select this with

bazel test ... --test_filter HiMom*
or
bazel test ... --test_filter Hi*
