Speeding up the edit-compile-test cycle

Rerunning failed tests only

When running tests, it is possible to only run tests that have failed in a previous test run. This can help to:

• speed up the edit-compile-test cycle
• focus on a fixed subset of failing tests

Two options are required for this.

Instruct Hspec to write/read failure reports to/from a file:

echo --failure-report .hspec-failures >> ~/.hspec

Enable --rerun:

echo --rerun >> ~/.hspec

In addition --rerun-all-on-success is useful in this scenario:

echo --rerun-all-on-success >> ~/.hspec

You may want to have a look at the section on options for more details.
