.PHONY: _build
_build:
	set -o pipefail && \
	xcodebuild build -workspace $(WORKSPACE).xcworkspace -scheme $(SCHEME) \

.PHONY: _test
_test:
	set -o pipefail && \
	xcodebuild test -workspace $(WORKSPACE).xcworkspace -scheme $(SCHEME) \

				xcpretty --color --report junit --output $(CIRCLE_TEST_REPORTS)/test-results.xml

Invoked from circle.yml with something like this:

test:
  override:
    - make build
    - make test

We do a similar thing: build and run tests

We even have a 15 second wait between build + test, and pre-launch the right sim
