我正在尝试创建一个rake任务,用于Rails 4.0.2(Ruby 2.2.3)项目中创建测试数据库,插入种子数据,然后运行测试套件,最后通过删除测试数据库来清理工作。以下是一个简单的示例:
task better_test: :environment do
Rake::Task["test:setup"].execute
Rake::Task["test"].execute
Rake::Task["test:cleanup"].execute
end
上述任务确实调用了
test:setup
rake任务(创建/填充测试数据库),然后调用test
rake任务,并最终调用test:cleanup
rake任务。然而,问题在于上一次的test:cleanup
被调用时,test
rake任务还没有完成运行。是否有办法在之前任务完成后调用清理rake任务呢?以下是使用trace运行任务的输出:
$ RAILS_ENV=test be rake better_test --trace

Finished tests in 0.037493s, 160.0278 tests/s, 106.6852 assertions/s.
从结果可以看出,任务是按顺序调用的,但清理任务在测试完成之前就执行了。有什么想法来解决这个问题吗?
