蝙蝠assert_failure测试没有识别出口1？

Question

在尝试测试一种检查GitLab服务器是否运行5秒的方法时，我在检测错误消息时遇到了一些困难。

功能检查GitLab服务器状态

check_for_n_seconds_if_gitlab_server_is_running() {
    duration=$1
    echo "duration=$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

我希望测试能够通过，因为exit 1已经到达，而且我认为它会导致失败。

观察到的行为

当包含出口1时，测试失败，测试的输出为：

如果卸载后5秒内没有运行

服务器，则引发GitLab✗错误。

当exit 1被注释掉时，测试失败，测试的输出是：

✗ 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

如何确保测试检测抛出的错误?/如何抛出error/exit 1命令以确保assert_failure测试通过？

Answer 1

问题是，我试图从测试函数中运行一个函数，而不是从单独的bash运行。我是通过复制另一个使用run bash -c命令的工作示例来发现的，该命令在相同的函数上的行为确实与预期的一样。因此，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=$1
    echo "duration=$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

通过通过run bash -c命令调用函数，测试通过：

如果卸载后5秒内没有运行

服务器，则引发GitLab✓错误。

1次测试，0次失败

备注

如果有人能够包含一个不通过单独的run bash -c命令调用函数而工作的MWE，但直接从测试函数中调用该函数，请将其作为单独的答案发布。
