Question

我有一个绿色测试：

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

test_study_page_&_question_screen                               PASS (0.27s)

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

因为我在同一页面上有很多（页面上）Javascript代码，我也想测试。因此，我告诉Capybara使用能够使用Javascript的驱动程序。例如webkit，但我也尝试了吵闹和硒。

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，测试是红色的。虽然我没有做任何事情，只是改变了司机。

Capybara::ExpectationNotMet:         Capybara::ExpectationNotMet: expected "" to include "Study | Word Up"

这怎么可能？

Answer 1

经过一些测试后，我认为您正在访问设置方法中的根路径。因此，您的测试访问根路径，然后更改Capybara驱动程序。尝试更改驱动程序，然后访问根路径。

基本上，添加

visit root_path

后

Capybara.javascript_driver = :webkit
Capybara.current_driver = Capybara.javascript_driver

这失败了：

setup do
    visit root_path
end

test "study page & question screen" do
    Capybara.javascript_driver = :webkit
    Capybara.current_driver = Capybara.javascript_driver
    assert_title "Study | Word Up"
end

通过：

setup do
end

test "study page & question screen" do
    Capybara.javascript_driver = :webkit
    Capybara.current_driver = Capybara.javascript_driver
    visit root_path
    assert_title "Study | Word Up"
end

Minitest / Capybara：切换到JS驱动程序时，绿色测试变为红色
