have_performed_job 匹配器

have_performed_job（也称为 perform_job）匹配器用于检查是否执行了给定的 ActiveJob 作业。

背景

假设活动作业可用。

检查作业类名

假设一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件

require "rails_helper"

RSpec.describe UploadBackupsJob do
  it "matches with performed job" do
    ActiveJob::Base.queue_adapter = :test
    ActiveJob::Base.queue_adapter.perform_enqueued_jobs = true
    expect {
      UploadBackupsJob.perform_later
    }.to have_performed_job(UploadBackupsJob)
  end
end

当我运行 rspec spec/jobs/upload_backups_job_spec.rb

则示例应全部通过。

检查传递给作业的参数

假设一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件

require "rails_helper"

RSpec.describe UploadBackupsJob do
  it "matches with performed job" do
    ActiveJob::Base.queue_adapter = :test
    ActiveJob::Base.queue_adapter.perform_enqueued_jobs = true
    expect {
      UploadBackupsJob.perform_later("users-backup.txt", "products-backup.txt")
    }.to have_performed_job.with("users-backup.txt", "products-backup.txt")
  end
end

当我运行 rspec spec/jobs/upload_backups_job_spec.rb

则示例应全部通过。

检查作业执行时间

假设一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件

require "rails_helper"

RSpec.describe UploadBackupsJob do
  it "matches with performed job" do
    ActiveJob::Base.queue_adapter = :test
    ActiveJob::Base.queue_adapter.perform_enqueued_jobs = true
    ActiveJob::Base.queue_adapter.perform_enqueued_at_jobs = true
    expect {
      UploadBackupsJob.set(:wait_until => Date.tomorrow.noon).perform_later
    }.to have_performed_job.at(Date.tomorrow.noon)
  end
end

当我运行 rspec spec/jobs/upload_backups_job_spec.rb

则示例应全部通过。

检查作业队列名称

假设一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件

require "rails_helper"

RSpec.describe UploadBackupsJob do
  it "matches with performed job" do
    ActiveJob::Base.queue_adapter = :test
    ActiveJob::Base.queue_adapter.perform_enqueued_jobs = true
    expect {
      UploadBackupsJob.perform_later
    }.to have_performed_job.on_queue("default")
  end
end

当我运行 rspec spec/jobs/upload_backups_job_spec.rb

则示例应全部通过。

使用别名方法

假设一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件

require "rails_helper"

RSpec.describe UploadBackupsJob do
  it "matches with performed job" do
    ActiveJob::Base.queue_adapter = :test
    ActiveJob::Base.queue_adapter.perform_enqueued_jobs = true
    expect {
      UploadBackupsJob.perform_later
    }.to perform_job(UploadBackupsJob)
  end
end

当我运行 rspec spec/jobs/upload_backups_job_spec.rb

则示例应全部通过。
