Bazel Codelab

Before you get started

Take a look at these informational slides to learn about Bazel.

Section 1: Hello, Bazel!

1. Edit: java/src/main/java/bazel/bootcamp/BUILD
2. Add a java_binary target for the HelloBazelBootcamp.java file
   • java_binary documentation
3. Run the binary using bazel run //java/src/main/java/bazel/bootcamp:HelloBazelBootcamp

Section 2: Go server

1. The Go BUILD files can be fully generated by Gazelle. Run gazelle with bazel run //:gazelle
2. Run the go binary using bazel run //go/cmd/server
3. Go to http://localhost:8081 to see results (there won't be any logs yet): curl http://localhost:8081

Section 3: Java client

1. Edit the BUILD file for logger.proto
   • java_proto_library documentation
   • java_grpc_library documentation (look towards the bottom of the page for Bazel related documentation)
2. Edit the BUILD file for JavaLoggingClientLibrary.java
   • java_library documentation
3. Edit the BUILD file for JavaLoggingClient.java
   • java_binary documentation
4. bazel run the Java binary you wrote
5. bazel run the Go binary from Section 2
6. Send messages from the client to the server and view them on http://localhost:8081

Section 4: Java client unit tests

1. Edit the BUILD file for JavaLoggingClientLibraryTest.java
   • java_test documentation
   Hint

   Names matter for tests. The java_test for this file should be named JavaLoggingClientLibraryTest
2. Edit the BUILD file for JavaLoggingClientTest.java
3. Run the tests using bazel test

Section 6: Integration test

1. Edit the BUILD file for integrationtest.sh
   • sh_test documentation
2. Run the test using bazel test and make sure that it passes
3. Run the test using bazel test <target> --runs_per_test=10 and make sure that it passes
   Hint

   You may need to modify the BUILD file again to make this work
