rewriter

Documentation

Overview

Rewriter will take one or more existing Go test files on the command-line and rewrite "goconvey" tests in them to use go.chromium.org/luci/common/testing/ftt.

This makes the following changes:

• Converts all Convey function calls to ftt.Run calls. This will also rewrite the callback from `func() {...}` to `func(t *ftt.Test) {...}`. If the test already had an explicit context variable (e.g. `func(c C)`), this will preserve that name.
• Removes dot-imported convey.
• Adds imports for go.chromium.org/luci/testing/common/truth/assert and go.chromium.org/luci/testing/common/truth/should.
• Rewrites So and SoMsg calls.

Note that 'fancy' uses of Convey/So will likely be missed by this tool, and will require hand editing... however this does complete successfully for all code in luci-go, infra and infra_internal at the time of writing.
