How to `go test` in sub-directories only tests matching a given pattern?

问题

在我的项目中，我有多个包和子目录。在顶级目录中，我可以运行go test ./...来运行所有子目录中的所有测试。我已经阅读了相当长的时间，了解如何只测试与给定模式或测试名称匹配的测试，但是无法找到解决方案。通过阅读这些（1 2 3和godocs），我认为我可以使用以下命令：

  1. go test ./... -run mypattern

来运行与mypattern匹配的测试，但是对我来说它运行了所有的测试。目前，我正在使用cd、find和grep的组合来运行符合我的条件的测试。

你可以尝试这样做：

  1. git clone https://github.com/grafana/grafana-plugin-sdk-go.git
  2. > go test -run TestJSON
  3. === RUN   TestJSONNotice
  4. === RUN   TestJSONNotice/notice_with_severity_and_text
  5. --- PASS: TestJSONNotice (0.00s)
  6.     --- PASS: TestJSONNotice/notice_with_severity_and_text (0.00s)
  7. === RUN   TestJSON
  8. === RUN   TestJSON/json.Unmarshal_and_json.Marshal
  9. === RUN   TestJSON/json.Unmarshal_and_json.Marshal/Should_run_without_error
  10. === RUN   TestJSON/json.Unmarshal_and_json.Marshal/Should_create_equal_data
  11. --- PASS: TestJSON (0.00s)
  12.     --- PASS: TestJSON/json.Unmarshal_and_json.Marshal (0.00s)
  13.         --- PASS: TestJSON/json.Unmarshal_and_json.Marshal/Should_run_without_error (0.00s)
  14.         --- PASS: TestJSON/json.Unmarshal_and_json.Marshal/Should_create_equal_data (0.00s)
  15. PASS
  16. ok      github.com/grafana/grafana-plugin-sdk-go/data   0.016s
  18. > cd data
  20. > go test -run *TestJSON*
  21.   zsh: no matches found: *TestJSON*
  23. > go test -run ^TestJSON*
  24.   zsh: no matches found: ^TestJSON*
  26. > go test -v -cover --short -race  ./... -run ^TestFloatAt*
  27.   zsh: no matches found: ^TestFloatAt*

有人能告诉我如何只测试与给定模式或测试名称匹配的测试吗？

英文:

In my project I have multiple packages and sub-directories. In top directory, I can run go test ./... and it runs all the tests in all sub-directories. I have been reading for quite some time on how test only tests matching a given pattern or test name but unable to find a solution. By going through these (1 2 3 and godocs) I thought I could use this:

  1. go test ./... -run mypattern

to run tests matching mypattern but for me it runs all the tests. For now I am using a combination of cd, find and grep to run tests matching my criteria.

You can try this:

  1. git clone https://github.com/grafana/grafana-plugin-sdk-go.git  
  2. > go test -run TestJSON  
  3. === RUN   TestJSONNotice
  4. === RUN   TestJSONNotice/notice_with_severity_and_text
  5. --- PASS: TestJSONNotice (0.00s)
  6.     --- PASS: TestJSONNotice/notice_with_severity_and_text (0.00s)
  7. === RUN   TestJSON
  8. === RUN   TestJSON/json.Unmarshal_and_json.Marshal
  9. === RUN   TestJSON/json.Unmarshal_and_json.Marshal/Should_run_without_error
  10. === RUN   TestJSON/json.Unmarshal_and_json.Marshal/Should_create_equal_data
  11. --- PASS: TestJSON (0.00s)
  12.     --- PASS: TestJSON/json.Unmarshal_and_json.Marshal (0.00s)
  13.         --- PASS: TestJSON/json.Unmarshal_and_json.Marshal/Should_run_without_error (0.00s)
  14.         --- PASS: TestJSON/json.Unmarshal_and_json.Marshal/Should_create_equal_data (0.00s)
  15. PASS
  16. ok      github.com/grafana/grafana-plugin-sdk-go/data   0.016s
  18. > cd data
  20. > go test -run *TestJSON*  
  21.   zsh: no matches found: *TestJSON*  
  23. > go test -run ^TestJSON*  
  24.   zsh: no matches found: ^TestJSON*
  25.     
  26. > go test -v -cover --short -race  ./... -run ^TestFloatAt*  
  27.   zsh: no matches found: ^TestFloatAt*

Can someone please tell me how test only tests matching a given pattern or test name?

传递与您的测试名称匹配的正则表达式应该运行匹配的测试...

例如：

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

在项目中运行以TestError开头的不同测试...

  1. ?       github.com/user/project/internal/rabbitmq       [没有测试文件]
  2. === RUN   TestErrorMiddleware
  3.     printer.go:54: GET http://localhost:45678/surprise
  4. ⇨ http服务器已在[::]:45678上启动
  5. {"error":{"code":"EXPECTED","status":418},"level":"warning","msg":"expected: here's tea","time":"2021-08-06T17:25:58+03:00"}
  6. --- PASS: TestErrorMiddleware (0.01秒)
  7. PASS
  8. 覆盖率：语句的54.8%
  9. ok      ithub.com/user/project/internal/datadog        3.725秒  覆盖率：语句的70.6%
  10. ?       github.com/user/project/internal/ftp    [没有测试文件]
  11. ?       github.com/user/project/internal/mongo  [没有测试文件]
  12. testing: 警告：没有要运行的测试
  13. PASS
  14. 覆盖率：语句的0.0%
  15. ok      github.com/user/project/postgres       3.704秒  覆盖率：语句的0.0% [没有要运行的测试]
  16. ok      github.com/user/project/escrow  7.784秒  覆盖率：语句的0.0% [没有要运行的测试]
  17. === RUN   TestError
  18. --- PASS: TestError (0.00秒)
  19. === RUN   TestErrorHandling
  20. --- PASS: TestErrorHandling (0.00秒)
  21. PASS
  22. 覆盖率：语句的70.6%
  23. ...

您的目标是测试的名称（以Test开头的函数名称）

英文:

Passing regular expression that fits name of your test should run matched tests...

for examples:

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

runs different tests that's start with TestError in the project...

  1. ?       github.com/user/project/internal/rabbitmq       [no test files]
  2. === RUN   TestErrorMiddleware
  3.     printer.go:54: GET http://localhost:45678/surprise
  4. ⇨ http server started on [::]:45678
  5. {"error":{"code":"EXPECTED","status":418},"level":"warning","msg":"expected: here's tea","time":"2021-08-06T17:25:58+03:00"}
  6. --- PASS: TestErrorMiddleware (0.01s)
  7. PASS
  8. coverage: 54.8% of statements
  9. ok      ithub.com/user/project/internal/datadog        3.725s  coverage: 70.6% of statements
  10. ?       github.com/user/project/internal/ftp    [no test files]
  11. ?       github.com/user/project/internal/mongo  [no test files]
  12. testing: warning: no tests to run
  13. PASS
  14. coverage: 0.0% of statements
  15. ok      github.com/user/project/postgres       3.704s  coverage: 0.0% of statements [no tests to run]
  16. ok      github.com/user/project/escrow  7.784s  coverage: 0.0% of statements [no tests to run]
  17. === RUN   TestError
  18. --- PASS: TestError (0.00s)
  19. === RUN   TestErrorHandling
  20. --- PASS: TestErrorHandling (0.00s)
  21. PASS
  22. coverage: 70.6% of statements
  23. ...

what you targeting is a name of the test (function name that starts with Test)
