我同意jsunit在藤上死去。我们刚完成使用YUI Test进行替换。
与使用qUnit的示例类似,我们使用Selenium运行测试。我们正在独立于我们的其他硒测试运行此测试,因为它没有正常的UI回归测试所具有的依赖性(例如将应用程序部署到服务器)。
首先,我们有一个基本的JavaScript文件,包含在我们所有的测试html文件中。这可以处理设置YUI实例,测试运行器,YUI.Test.Suite对象以及Test.Case。它有一个可以通过Selenium访问的方法来运行测试套件,检查测试运行器是否仍在运行(结果在完成后才可用),并获取测试结果(我们选择了JSON格式)
var yui_instance; //the YUI instance
var runner; //The YAHOO.Test.Runner
var Assert; //an instance of YAHOO.Test.Assert to save coding
var testSuite; //The YAHOO.Test.Suite that will get run.
/**
* Sets the required value for the name property on the given template, creates
* and returns a new YUI Test.Case object.
*
* @param template the template object containing all of the tests
*/
function setupTestCase(template) {
template.name = "jsTestCase";
var test_case = new yui_instance.Test.Case(template);
return test_case;
}
/**
* Sets up the test suite with a single test case using the given
* template.
*
* @param template the template object containing all of the tests
*/
function setupTestSuite(template) {
var test_case = setupTestCase(template);
testSuite = new yui_instance.Test.Suite("Bond JS Test Suite");
testSuite.add(test_case);
}
/**
* Runs the YAHOO.Test.Suite
*/
function runTestSuite() {
runner = yui_instance.Test.Runner;
Assert = yui_instance.Assert;
runner.clear();
runner.add(testSuite);
runner.run();
}
/**
* Used to see if the YAHOO.Test.Runner is still running. The
* test results are not available until it is done running.
*/
function isRunning() {
return runner.isRunning();
}
/**
* Gets the results from the YAHOO.Test.Runner
*/
function getTestResults() {
return runner.getResults(yui_instance.Test.Format.JSON);
}
至于事情的硒一面,我们使用了参数化测试。我们在数据方法中在IE和FireFox中运行我们的测试,将测试结果解析成对象数组列表,每个数组包含浏览器名称,测试文件名称,测试名称,结果(通过,失败或忽略)和消息。
实际测试只声明测试结果。如果它不等于“通过”,则它将通过从YUI测试结果返回的消息进行测试失败。
@Parameters
public static List<Object[]> data() throws Exception {
yui_test_codebase = "file:///c://myapppath/yui/tests";
List<Object[]> testResults = new ArrayList<Object[]>();
pageNames = new ArrayList<String>();
pageNames.add("yuiTest1.html");
pageNames.add("yuiTest2.html");
testResults.addAll(runJSTestsInBrowser(IE_NOPROXY));
testResults.addAll(runJSTestsInBrowser(FIREFOX));
return testResults;
}
/**
* Creates a selenium instance for the given browser, and runs each
* YUI Test page.
*
* @param aBrowser
* @return
*/
private static List<Object[]> runJSTestsInBrowser(Browser aBrowser) {
String yui_test_codebase = "file:///c://myapppath/yui/tests/";
String browser_bot = "this.browserbot.getCurrentWindow()"
List<Object[]> testResults = new ArrayList<Object[]>();
selenium = new DefaultSelenium(APPLICATION_SERVER, REMOTE_CONTROL_PORT, aBrowser.getCommand(), yui_test_codebase);
try {
selenium.start();
/*
* Run the test here
*/
for (String page_name : pageNames) {
selenium.open(yui_test_codebase + page_name);
//Wait for the YAHOO instance to be available
selenium.waitForCondition(browser_bot + ".yui_instance != undefined", "10000");
selenium.getEval("dom=runYUITestSuite(" + browser_bot + ")");
//Output from the tests is not available until
//the YAHOO.Test.Runner is done running the suite
selenium.waitForCondition("!" + browser_bot + ".isRunning()", "10000");
String output = selenium.getEval("dom=getYUITestResults(" + browser_bot + ")");
JSONObject results = JSONObject.fromObject(output);
JSONObject test_case = results.getJSONObject("jsTestCase");
JSONArray testCasePropertyNames = test_case.names();
Iterator itr = testCasePropertyNames.iterator();
/*
* From the output, build an array with the following:
* Test file
* Test name
* status (result)
* message
*/
while(itr.hasNext()) {
String name = (String)itr.next();
if(name.startsWith("test")) {
JSONObject testResult = test_case.getJSONObject(name);
String test_name = testResult.getString("name");
String test_result = testResult.getString("result");
String test_message = testResult.getString("message");
Object[] testResultObject = {aBrowser.getCommand(), page_name, test_name, test_result, test_message};
testResults.add(testResultObject);
}
}
}
} finally {
//if an exception is thrown, this will guarantee that the selenium instance
//is shut down properly
selenium.stop();
selenium = null;
}
return testResults;
}
/**
* Inspects each test result and fails if the testResult was not "pass"
*/
@Test
public void inspectTestResults() {
if(!this.testResult.equalsIgnoreCase("pass")) {
fail(String.format(MESSAGE_FORMAT, this.browser, this.pageName, this.testName, this.message));
}
}
我希望这是有帮助的。
