How to break test when go test FAIL?

[thinkerou]

ref #1656

Now run make test script:

test:
	echo "mode: count" > coverage.out
	for d in $(TESTFOLDER); do \
		$(GO) test -v -covermode=count -coverprofile=profile.out $$d; \
		if [ -f profile.out ]; then \
			cat profile.out | grep -v "mode:" >> coverage.out; \
			rm profile.out; \
		fi; \
	done

If use $(GO) test -v -covermode=count -coverprofile=profile.out $$d; | grep "^--- FAIL" | exit 1;, it can output log to console.

So, how should we?
