如何将Golang测试用例的测试覆盖率值与特定阈值进行比较

发布于06月30日

我想要获得测试覆盖率，并与用户定义的阈值进行比较.我在Makefile中try 了下面的代码，我引用了这个link.它是在.yml文件中编写的，但我正在try 将其写入Makefile中.

.PHONY: lint    
testcoverage=$(go tool cover -func coverage.out | grep total | grep -Eo '[0-9]+\.[0-9]+')
echo ${testcoverage}
if (${testcoverage} -lt 50 ); then \
  echo "Please add more unit tests or adjust threshold to a lower value."; \
  echo "Failed"
  exit 1
else \
  echo "OK"; \
fi

它不会在echo ${totaltestcoverage}上打印任何内容，即使我的总覆盖率是40，它的答案也是OK.

有谁能帮我找到一种更好的方法来获得测试覆盖率，并与用户定义的阈值进行比较？

先谢谢你.

你可以试试这个

.PHONY: lint

testcoverage := $(shell go tool cover -func=coverage.out | grep total | grep -Eo '[0-9]+\.[0-9]+')
threshold = 50

test:
    @go test -coverprofile=coverage.out -covermode=count  ./...

check-coverage:
    @echo "Test coverage: $(testcoverage)"
    @echo "Test Threshold: $(threshold)"
    @echo "-----------------------"

    @if [ "$(shell echo "$(testcoverage) < $(threshold)" | bc -l)" -eq 1 ]; then \
        echo "Please add more unit tests or adjust the threshold to a lower value."; \
        echo "Failed"; \
        exit 1; \
    else \
        echo "OK"; \
    fi
