have_enqueued_job 匹配器

have_enqueued_job（也称为 enqueue_job）匹配器用于检查给定的 ActiveJob 作业是否已排队。

背景

给定 活动作业可用。

检查作业类名

给定 一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件，其中包含

require "rails_helper"

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

当 我运行 rspec spec/jobs/upload_backups_job_spec.rb

那么 示例应该全部通过。

检查传递给作业的参数

给定 一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件，其中包含

require "rails_helper"

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

当 我运行 rspec spec/jobs/upload_backups_job_spec.rb

那么 示例应该全部通过。

使用块检查传递给作业的参数

给定 一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件，其中包含

require "rails_helper"

RSpec.describe UploadBackupsJob do
  it "matches with enqueued job" do
    ActiveJob::Base.queue_adapter = :test
    expect {
      UploadBackupsJob.perform_later('backups.txt', rand(100), 'uninteresting third argument')
    }.to have_enqueued_job.with { |file_name, seed|
      expect(file_name).to eq 'backups.txt'
      expect(seed).to be < 100
    }
  end
end

当 我运行 rspec spec/jobs/upload_backups_job_spec.rb

那么 示例应该全部通过。

检查作业排队时间

给定 一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件，其中包含

require "rails_helper"

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

当 我运行 rspec spec/jobs/upload_backups_job_spec.rb

那么 示例应该全部通过。

检查作业排队是否没有等待

给定 一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件，其中包含

require "rails_helper"

RSpec.describe UploadBackupsJob do
  it "matches with enqueued job" do
    ActiveJob::Base.queue_adapter = :test
    expect {
      UploadBackupsJob.perform_later
    }.to have_enqueued_job.at(:no_wait)
  end
end

当 我运行 rspec spec/jobs/upload_backups_job_spec.rb

那么 示例应该全部通过。

检查作业队列名称

给定 一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件，其中包含

require "rails_helper"

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

当 我运行 rspec spec/jobs/upload_backups_job_spec.rb

那么 示例应该全部通过。

使用别名方法

给定 一个名为“spec/jobs/uploadbackupsjob_spec.rb”的文件，其中包含

require "rails_helper"

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

当 我运行 rspec spec/jobs/upload_backups_job_spec.rb
