How to run a single unit test?

[knightXun]

For example, if I want to run the case

xla/xla/service/algebraic_simplifier_test.cc

Line 119 in 0fbf2e1

TEST_F(AlgebraicSimplifierTest, IsNonNegative_Op) {

what steps shoud i do?

[beckerhe]

bazel test --test_filter=AlgebraicSimplifierTest.IsNonNegative_Op //xla/service:algebraic_simplifier_test should do that for you.

If I add some std::cout to print log, How can I see them when I run the test ?

[beckerhe]

If you add --test_output=all to the bazel command you should see the output.
