BATS assert_failure 测试无法识别出口 1？

Question

在尝试测试一种检查 GitLab 服务器是否运行的方法时，我在检测错误消息时遇到了一些困难。

检查 GitLab 服务器状态的功能

check_for_n_seconds_if_gitlab_server_is_running() {
    duration=
    echo "duration=$duration"
    running="false"
    if [ "$running" == "false" ]; then
        echo "ERROR, did not find the GitLab server running within $duration seconds!"
        exit 1
    fi
}

测试代码

#!./test/libs/bats/bin/bats

load 'libs/bats-support/load'
load 'libs/bats-assert/load'
load 'libs/bats-file/load'

source src/helper.sh


@test "If error is thrown if the GitLab server is not running within 5 seconds after uninstallation." {
        
    # run the tested method
    check_for_n_seconds_if_gitlab_server_is_running 4
    
    assert_failure
    assert_output --partial "ERROR, did not find the GitLab server running within 4 seconds!"
}

预期行为

我希望测试通过，因为达到 exit 1 并且我认为它会引发失败。

观察到的行为

当包含出口1时，测试失败，测试输出为：

✗ If error is thrown if the GitLab server is not running within 5 seconds after uninstallation.

当exit 1被注释掉时，测试失败，测试输出为：

✗ If error is thrown if the GitLab server is not running within 5 seconds after uninstallation.
   (from function `assert_failure' in file test/libs/bats-assert/src/assert.bash, line 140,
    in test file test/long_test_helper.bats, line 17)
     `assert_failure' failed
   duration=4
   ERROR, did not find the GitLab server running within 4 seconds!
   
   -- command succeeded, but it was expected to fail --
   output : 
   --

问题

如何确保测试检测到抛出的错误？/我应该如何抛出错误/exit 1 命令以确保 assert_failure 测试通过？

Answer 1

问题是我试图运行来自测试函数的函数，而不是来自单独的 bash shell 的函数。我通过重现另一个使用 run bash -c 命令的工作示例发现了这一点，该命令在同一函数上的行为确实符合预期。所以在实践中，以下工作：

测试代码

#!./test/libs/bats/bin/bats

load 'libs/bats-support/load'
load 'libs/bats-assert/load'
load 'libs/bats-file/load'

@test "If error is thrown if the GitLab server is not running within 5 seconds after uninstallation." {
    
    run bash -c "source src/helper.sh && check_for_n_seconds_if_gitlab_server_is_running"
    assert_failure 
    assert_output --partial "ERROR, did not find the GitLab server running within 4 seconds!"
}

测试功能代码

check_for_n_seconds_if_gitlab_server_is_running() {
    duration=
    echo "duration=$duration"
    running="false"
    if [ "$running" == "false" ]; then
        echo "ERROR, did not find the GitLab server running within $duration seconds!"
        exit 1
    fi
}

预期行为

通过 run bash -c 命令调用函数，测试通过：

✓ If error is thrown if the GitLab server is not running within 5 seconds after uninstallation.

1 test, 0 failures

备注

如果有人能够包含无需从单独的 run bash -c 命令调用函数即可工作的 MWE，而是直接作为测试函数中的函数，请 post 将其作为单独的回答。
