该错误最近开始在我的摩卡测试套件中出现，到目前为止，我发现的答案并不能真正帮助理解问题所在。
我得到的错误是：
/var/lib/jenkins/workspace/test_suite/test/integration/adds_image_and_confirms_style_via_edit_button.js

看着https://romaklimenko.github.io/curves/docs/mocha.html，我不确定ret是什么，所以我看不出问题出在哪里。测试看起来像这样，但这在其他测试中也会发生，并且这些测试以前还不错，所以不确定如何调试。任何意见将是有益的。我还应该提到这是在我的Jenkins服务器上发生的，并且只有在本地运行测试时才偶尔发生。
Test.describe("Adds image and confirms style via edit button\n", function() {
this.timeout(mochaTimeOut);
Test.before(function(done) {
kTest.logFilename(__filename);
kTest.setup().then(function() {
return Factory.createA({
...
});
}).then(function () {
return Factory.createB({
...
});
}).then(function () {
return Factory.createC({
...

}).then(function () {
return Factory.createD({
...
});
}).then(function () {
kTest.login(testVariables.email, testVariables.password);
}).then(function () {
var elementSelector = 'h3';
var element = kTest.driver.findElement(By.css(elementSelector));
element.getText().then(function(text) {
assert.equal(text, "Enter your pin");
});
}).then(function() {
return adminDb.Users.findOne({userId: testVariables.userId});
}).then(function(admin) {
kTest.enterPin(admin.textPin, testVariables.password);
}).then(function() {
var button = kTest.driver.wait(until.elementLocated(By.className('fa-bars')), K_TEST_TIMEOUT);
button.click();
kTest.driver.findElement(By.className("side_menu_q")).click();
kTest.driver.wait(until.elementLocated(By.id("selectOption")), K_TEST_TIMEOUT);
var elementSelector = "h4";
var element = kTest.driver.findElement(By.css(elementSelector));
element.getText().then(function(val) {
assert.equal(val, "IMAGE NAMES");
});
}).then(function() {
done();
}).catch(function(err) {
throw err;
});
});
...
});
enableTimeouts无效，顺便说一句
