Question

在测试Javascript方面，我只是没有使用Minitest。希望我不会因为发出这么多问题而困扰任何人。

所以，现在我设法让Capybara工作，并且能够用新语法替换（部分）我现有的测试（因为正常的Minitest断言不适用于Capybara）。

test "study page & question screen" do

    assert_title "Study | Word Up"
    assert page.has_selector?('h3', text: "STUDY"), "Panel title missing or wrong"
    assert page.has_selector?("div.progress-bar"), "Progress bar missing or with wrong class"
end

测试是绿色的，都很好。

test_answer_screen                                              PASS (0.98s)
test_study_page_&_question_screen                               PASS (0.27s)

Finished in 1.26314s
2 tests, 2 assertions, 0 failures, 0 errors, 0 skips

现在是Javascript部分。我想测试是否存在我使用页面Javascript加载的span元素。因此，我将驱动程序切换为使用能够使用JS的驱动程序。

test "study page & question screen" do

    Capybara.javascript_driver = :webkit
    Capybara.current_driver = Capybara.javascript_driver
    assert_title "Study | Word Up"
    assert page.has_selector?('h3', text: "STUDY"), "Panel title missing or wrong"
    assert page.has_selector?("div.progress-bar"), "Progress bar missing or with wrong class"
end

突然之间的测试是红色的，因为第一个期望神秘地没有得到满足。（甚至没有尝试测试JS内容）

16:28:21 - INFO - Running: test/integration/study/study_test.rb

StudyTest
test_answer_screen                                              PASS (1.12s)
test_study_page_&_question_screen                              ERROR (5.11s)
Capybara::ExpectationNotMet:         Capybara::ExpectationNotMet: expected "" to include "Study | Word Up"

但是，如果这不够奇怪，当取出所有非JS测试并且仅测试我通过页面JS插入的元素时：

test "study page & question screen" do

    Capybara.javascript_driver = :webkit
    Capybara.current_driver = Capybara.javascript_driver
    #assert_title "Study | Word Up"
    #assert page.has_selector?('h3', text: "STUDY"), "Panel title missing or wrong"
    #assert page.has_selector?("div.progress-bar"), "Progress bar missing or with wrong class"
    assert page.has_selector?('span'), "Frontside missing or wrong" 
end

我得到了一个失败的测试：

16:49:06 - INFO - Running: test/integration/study/study_test.rb

StudyTest
test_answer_screen                                              PASS (0.99s)
test_study_page_&_question_screen                               FAIL (4.19s)
Minitest::Assertion:         Frontside missing or wrong

现在，我觉得我在随机尝试方法和驱动程序的组合，我不知道从现在开始到哪里去。它只是我还是minitest和提到的宝石的文档有点过于紧凑。我希望我不会冒犯任何人，或者这样说。可能只是因为我在使用宝石和组合它们方面没有太多经验。

在Minitest中，切换到JS驱动程序会使断言失败
