ruby-on-rails - Minitest 第一次失败退出？

Question

我在 Rails 中使用 Minitest。

如果我正在运行一堆测试，我如何让它在第一次失败时退出？我希望在编写测试时发生这种情况，因为在失败的测试之后运行后续测试是浪费时间。

我刚刚在搜索解决方案时找到了这个答案，但至少在 Rails 5.1 中你有一个选择:

rails test -h Usage: bin/rails test [options] [files or directories]

You can run a single test by appending a line number to a filename:

    bin/rails test test/models/user_test.rb:27

You can run multiple files and directories at the same time:

    bin/rails test test/controllers test/integration/login_test.rb

By default test failures and errors are reported inline during a run.

Rails options:
    -w, --warnings                   Run with Ruby warnings enabled
    -e, --environment                Run tests in the ENV environment
    -b, --backtrace                  Show the complete backtrace
    -d, --defer-output               Output test failures and errors after the test run
    -f, --fail-fast                  Abort test run on first failure or error
    -c, --[no-]color                 Enable color in the output

所以你只需要运行 rails test -f
