我可以让RSpec只运行更改的规格吗? [英] Can I get RSpec to only run changed specs?

问题描述

我有一个用于大型项目(约3800个单独示例)的测试套件，我将其从RSpec 2.14更新为3.6.

I have a test suite for a very large project (~ 3800 individual examples) that I'm updating from RSpec 2.14 to 3.6.

我刚刚为s/be_true/be true/运行了全部替换，但是其中一些应该改为be_truthy，并且这些规格失败了.

I have just run a replace-all for s/be_true/be true/, but some of them should be_truthy instead, and these specs are failing.

我可以通过一些工作从git diff中提取更改的行，但是随后我需要将这些行输入RSpec的config.filter_run中，而且似乎不希望我为locations过滤器做这件事(当您在命令行上指定rspec path/to/file:line时激活的那个)；它说"All examples were filtered out; ignoring {:locations=>...}".

I can extract the changed lines from git diff - with a little work - but then I need to feed these into RSpec's config.filter_run, and it doesn't seem to like me doing that for the locations filter (the one activated when you specify a rspec path/to/file:line on the command line); it says "All examples were filtered out; ignoring {:locations=>...}".

我也可以在around过滤器中使用example.run unless example.location.in? changed_specs，但是此skip将所有其他内容都标记为pending，而不是完全忽略它们.并且它不能与run_all_when_everything_filtered的其他过滤器配合使用. (可能是因为example.location指的是测试的第一行，但更改仅次于该行.)

I can also example.run unless example.location.in? changed_specs in an around filter, but this skips all the others and marks them as pending, rather than ignoring them completely; and it doesn't work in concert with the other filters to run_all_when_everything_filtered. (Probably because example.location refers to the top line of the test, but the changes are a few lines below that.)

我似乎也不能用它为example.metadata添加标签，然后将其过滤掉.

And I can't seem to use it to add a tag to the example.metadata and then filter it out, either.

我也不想在命令行上指定它们，因为我的测试在rerun下运行，该命令一直运行相同的命令.

I also don't want to specify them on the command line, because my tests run under rerun, which keeps running the same command.

还有其他想法吗?

推荐答案

您可以使用以下命令运行更改的规范:

You can run changed specs with:

rspec $(git ls-files --modified spec)

如果要包括新的未版本规范，请使用:

if you want include new unversioned specs as well use:

rspec $(git ls-files --modified --others spec)

您可以使用shell别名来简化此操作:

You can make this handier with a shell alias:

alias rch='rspec $(git ls-files --modified --others spec)'
