Jasmine with JS-Test-Driver
- 1. Problem Statement / TargetAbility to run JavaScript tests through commandline (not exactly headlessly)Integrate test results with the Bamboo build planVisibility of code-coverage
- 2. Options for JS test-runner toolsEnv.js and Rhino.jsV8 JavaScript EngineJasmine-Maven plug-inJasmine-Ruby plug-inJasmine-JsTestDriver
- 3. Env.js & Rhino.jsUses its own JS engineIs more closer to Mozilla FirefoxStill does not even behave as a mirror image of Firefox, on commandlineFindings: behaves as a different browser in itselfV8 JavaScript EngineGoogle's open source JavaScript engine, used in chromeIs a C++ code-base, needs to be compiled on local machinePretty capable, supports Mozilla and chrome, not sure about SafariFindings: Pretty capable, but have not explored much
- 4. Jasmine-Maven Plug-inUses HTMLUnit for headless browser runnerHTMLUnit’s only supports Firefox and IEFindings – not capable to mock Safari capabilitiesJasmine-Ruby Plug-inHas major issues with the “afterEach” and “toContains” Jasmine capabilitiesCan run with any browser – need to open the SpecRunner.html on the browser of choice !!!Findings – Promising, but needs to evolve
- 5. JsTestDriver
- 6. Why JsTestDriverCan run JS tests through commandline, on the browser(ant version) of choiceGenerates output in JUnit format, making it easier for Bamboo integrationWell compatible with JasminePossesses code-coverage capabilityHad certain minor issues, which have a workaround now
- 7. Workarounds required for JTDNot fully compatible with prototype.js – required jar fixJasmine spy issue, was unable to remove the spies – required Jasmine-JsTestDriver Adapter fixNever closes the browser tab when test-runner completes – added a minor apple-script fix

Creating test-append-areaQOWT.TEST.UTILS = function() { return { /** * creates dummy Test Append Area, and appends it to the document object, for running tests headlessly * While executing tests on Sumulat, you get "testAppendArea" div present in the html body itself. * But, in case of jsTestDriver, you do not have any such div present, and will have to create it on the fly. * @return testAppendArea div */createTestAppendArea: function() {vartestAppendAreaContainer = document.getElementById('testAppendArea'); if(testAppendAreaContainer === null) {testAppendAreaContainer = document.createElement("div");testAppendAreaContainer.innerHTML = '<div id="testAppendArea"></div>';document.body.insert(testAppendAreaContainer); } return document.getElementById('testAppendArea'); } };}();USAGE: (CommonContentMrg-test.js)testAppendArea = QOWT.TEST.UTILS.createTestAppendArea();testAppendArea.appendChild(rootNode);
- 10. Code-Coverage with JTDrake coveragehttp://quicknet/display/PROD/Generating+Code+Coverage+ReportsCoverage configurationsserver: http://localhost:9876load: - "../jasmine-1.0.1.js" - "../JasmineAdapter.js" - "../prototype-1.6.0.3.js" - "../../../dist/qowt-browser-doc-sheet.js" - "../../../dist/qowt-browser-point.js" - "../../../dist/qowt-browser-testsOnly.js"plugin: - name: "coverage" jar: "tools/jasmine-test-driver/plugins/coverage-1.2.2.jar" module: "com.google.jstestdriver.coverage.CoverageModule"

Debugging on JTDStart the server - java -Xms512m -Xmx1024m -jar tools/jasmine-test-driver/JsTestDriver-1.2.2.jar --port 9876Open the browser with the url- http://localhost:9876/captureRun the tests - java -Xms512m -Xmx1024m -jar tools/jasmine-test-driver/JsTestDriver-1.2.2.jar --tests allApply the breakpointRun the tests again
- 12. Known issue with JTDThe rake script fails to close Safari window, if it has the developer console opened !!!
