如何从 rails 测试套件运行单个测试?

How can I run a single test from a rails test suite?

rake test ANYTHING 似乎没有帮助.

推荐答案

注意: 这不会通过 rake 运行测试.所以你在 Rakefile 中的任何代码都不会被执行.

NOTE: This doesn't run the test via rake. So any code you have in Rakefile will NOT get executed.

要运行单个测试，请从 Rails 项目的主目录中使用以下命令:

To run a single test, use the following command from your rails project's main directory:

ruby -I test test/unit/my_model_test.rb -n test_name

这将运行一个名为name"的测试，该测试在指定文件的 MyModelTest 类中定义.test_name 是通过获取测试名称，在它前面加上单词test"，然后用下划线分隔单词而形成的.例如:

This runs a single test named "name", defined in the MyModelTest class in the specified file. The test_name is formed by taking the test name, prepending it with the word "test", then separating the words with underscores. For example:

class MyModelTest < ActiveSupport::TestCase test "valid with good attributes" do # do whatever you do end test "invalid with bad attributes" do # do whatever you do end end

您可以通过以下方式运行这两个测试:

You can run both tests via:

ruby -I test test/unit/my_model_test.rb

以及通过

ruby -I test test/unit/my_model_test.rb -n test_invalid_with_bad_attributes
