Bazel run vs test

Question

What's the difference between bazel test vs bazel run on the the java test rule? When I run the bazel run command, my test passes just fine, while with bazel test I get an error. If needed, I can provide more details, but I was interested in general differences between those two commands.

Answer 1

Bazel test launches the test in an isolated container. Due to this any default environment variable that were not explicitly set would not be available for test system. A typical example would be HELM_HOME being blank in bazel test.
