如何在子目录中“去测试”，只测试与给定模式匹配的测试？

Question

在我的项目中，我有多个包和子目录。在顶部目录中，我可以运行，它运行所有子目录中的所有测试。我已经阅读了很长一段时间，关于如何只测试与给定模式或测试名称匹配的测试，但无法找到解决方案。通过浏览这些（1 2 3和godocs），我想我可以使用这个：go test ./...go test ./... -run mypattern运行与 mypattern 匹配的测试，但对我来说，它运行所有测试。现在，我正在使用cd，查找和grep的组合来运行符合我标准的测试。你可以试试这个：git clone https://github.com/grafana/grafana-plugin-sdk-go.git  > go test -run TestJSON  === RUN   TestJSONNotice=== RUN   TestJSONNotice/notice_with_severity_and_text--- PASS: TestJSONNotice (0.00s)    --- PASS: TestJSONNotice/notice_with_severity_and_text (0.00s)=== RUN   TestJSON=== RUN   TestJSON/json.Unmarshal_and_json.Marshal=== RUN   TestJSON/json.Unmarshal_and_json.Marshal/Should_run_without_error=== RUN   TestJSON/json.Unmarshal_and_json.Marshal/Should_create_equal_data--- PASS: TestJSON (0.00s)    --- PASS: TestJSON/json.Unmarshal_and_json.Marshal (0.00s)        --- PASS: TestJSON/json.Unmarshal_and_json.Marshal/Should_run_without_error (0.00s)        --- PASS: TestJSON/json.Unmarshal_and_json.Marshal/Should_create_equal_data (0.00s)PASSok      github.com/grafana/grafana-plugin-sdk-go/data   0.016s> cd data> go test -run *TestJSON*    zsh: no matches found: *TestJSON*  > go test -run ^TestJSON*    zsh: no matches found: ^TestJSON*    > go test -v -cover --short -race  ./... -run ^TestFloatAt*    zsh: no matches found: ^TestFloatAt*有人可以告诉我如何只测试与给定模式或测试名称匹配的测试吗？

Answer 1

传递符合测试名称的正则表达式应运行匹配的测试...

例如：

go test -v -cover --short -race  ./... -run ^TestError*

运行不同的测试，这些测试从项目中的测试错误开始...
