为什么`测试 - 运行NotExist`传递? [英] Why does `go test -run NotExist` pass?
问题描述
如果我运行以下命令:
go test -run NotExist
答案是PASS。我认为我的测试文件不包含一个名为 TestNotExist
的测试,我希望上面的命令返回FAIL
-run
选项 go test
则运行所有测试。您可以使用 -run
选项来不运行所有测试;将过滤掉,排除 测试(并且您以形式要求不可排除测试的名称匹配 / em>正则表达式模式 - 但这与讨论的点无关):
默认情况下,go测试不需要参数。它使用当前目录中的源代码编译和测试软件包,包括测试,并运行测试。
-run regexp
只运行符合正则表达式的测试和示例。
这是一个完美的正常结果,所有的测试,即仍然需要执行的一组测试中仍然没有测试。
当没有测试失败时,它被认为是测试运行PASSes。如果没有测试匹配,则不会运行测试,也不会有测试失败,因此测试运行将通过。
If I run the following
go test -run NotExist
The response is PASS. Seeing as my test file does not contain a test called TestNotExist
I would expect the command above to return FAIL
Without the -run
option go test
runs all tests. You use the -run
option to not run all tests; to filter out, to exclude tests (and you do this in the form of requiring names of non-excludable tests to match a regexp pattern - but this is irrelevant form the point of discussion):
By default, go test needs no arguments. It compiles and tests the package with source in the current directory, including tests, and runs the tests.
-run regexp Run only those tests and examples matching the regular expression.
It is a perfectly "normal" outcome that a filtering filters out all tests, that no tests remains in the set of tests that still need to be executed.
When no tests FAIL, it is considered as the test run PASSes. If no tests match, no tests will run and no tests will FAIL, and thus the test run will PASS.
