Building

To check the code style and build binaries, you can simply run:

make build

Notice DM supports building with Go version Go >= 1.11.4, and unit test preparation can be found in Running/Unit Test

If you only want to build binaries, you can run:

make dm-worker  # build DM-worker

make dm-master  # build DM-master

make dmctl      # build dmctl

When DM is built successfully, you can find binaries in the bin directory.

Run Test

Run all tests, including unit test and integration test

make test
