have_enqueued_mail
匹配器
have_enqueued_mail
(也称为 enqueue_mail
)匹配器用于检查是否排队了给定的邮件程序。
背景
假设 存在活动作业。
检查邮件程序类和方法名称
假设 存在名为“spec/mailers/usermailerspec.rb”的文件,其中包含
require "rails_helper"
RSpec.describe NotificationsMailer do
it "matches with enqueued mailer" do
ActiveJob::Base.queue_adapter = :test
expect {
NotificationsMailer.signup.deliver_later
}.to have_enqueued_mail(NotificationsMailer, :signup)
end
end
当我运行 rspec spec/mailers/user_mailer_spec.rb
然后示例应该全部通过。
检查邮件程序排队时间
假设 存在名为“spec/mailers/usermailerspec.rb”的文件,其中包含
require "rails_helper"
RSpec.describe NotificationsMailer do
it "matches with enqueued mailer" do
ActiveJob::Base.queue_adapter = :test
expect {
NotificationsMailer.signup.deliver_later(wait_until: Date.tomorrow.noon)
}.to have_enqueued_mail.at(Date.tomorrow.noon)
end
end
当我运行 rspec spec/mailers/user_mailer_spec.rb
然后示例应该全部通过。
检查邮件程序参数
假设 存在名为“app/mailers/my_mailer.rb”的文件,其中包含
class MyMailer < ApplicationMailer
def signup(user = nil)
@user = user
mail to: "to@example.org"
end
end
假设 存在名为“spec/mailers/mymailerspec.rb”的文件,其中包含
require "rails_helper"
RSpec.describe MyMailer do
it "matches with enqueued mailer" do
ActiveJob::Base.queue_adapter = :test
# Works with plain args
expect {
MyMailer.signup('user').deliver_later
}.to have_enqueued_mail(MyMailer, :signup).with('user')
end
end
当我运行 rspec spec/mailers/my_mailer_spec.rb
然后示例应该全部通过。
参数化邮件程序
假设 存在名为“app/mailers/my_mailer.rb”的文件,其中包含
class MyMailer < ApplicationMailer
def signup
@foo = params[:foo]
mail to: "to@example.org"
end
end
假设 存在名为“spec/mailers/mymailerspec.rb”的文件,其中包含
require "rails_helper"
RSpec.describe MyMailer do
it "matches with enqueued mailer" do
ActiveJob::Base.queue_adapter = :test
# Works with named parameters
expect {
MyMailer.with(foo: 'bar').signup.deliver_later
}.to have_enqueued_mail(MyMailer, :signup).with(a_hash_including(params: {foo: 'bar'}))
end
end
当我运行 rspec spec/mailers/my_mailer_spec.rb
然后示例应该全部通过。
参数化并向邮件程序传递参数
假设 存在名为“app/mailers/my_mailer.rb”的文件,其中包含
class MyMailer < ApplicationMailer
def signup(user)
@user = user
@foo = params[:foo]
mail to: "to@example.org"
end
end
假设 存在名为“spec/mailers/mymailerspec.rb”的文件,其中包含
require "rails_helper"
RSpec.describe MyMailer do
it "matches with enqueued mailer" do
ActiveJob::Base.queue_adapter = :test
# Works also with both, named parameters match first argument
expect {
MyMailer.with(foo: 'bar').signup('user').deliver_later
}.to have_enqueued_mail(MyMailer, :signup).with(params: {foo: 'bar'}, args: ['user'])
end
end
当我运行 rspec spec/mailers/my_mailer_spec.rb
然后示例应该全部通过。
