from selenium test scripts back to selenese - selenium

I've got a bunch of test scripts written using Test::WWW::Selenium (but the fact that I used perl is inconsequential, any language selenium supports probably has the problem I describe). When the cogs in my application come loose I'd like to replay the test using the Selenium IDE, letting me have full control over the action
But I'm not sure how to go from my test script back into the selenium IDE, you can't paste perl into the IDE and have it transmogrify back to "HTML" (aka, internal selenium language, aka selenese). It was easy enough getting it out, alas.
The RemoteRunner has the command history in it, and I can copy and paste from this directly into selenium ide, and that would be great, but the history box will only hold 5 or 6 lines and clears itself! So it taunts me and is useless.
So how to log these more effectively? The logging options for the selenium rc (-browserSideLog, -log) don't seem to be helpful in this regard. I'm thinking of finding its RemoteRunner.html and hacking at it maybe so it won't clear that list, but is there another way?

It seems to be a not very common task but very interesting one. I do not think that there's some standard way so something has to be implemented.
I do not know Perl much and I use Java, so this is just a heads up:
I would extend the DefaultSelenium class for my tests that will use extended HttpCommandProcessor that will logs all commands performed:
import com.thoughtworks.selenium.HttpCommandProcessor;
public class ExtHttpCommandProcessor extends HttpCommandProcessor {
public ExtHttpCommandProcessor(String serverHost, int serverPort,
String browserStartCommand, String browserURL) {
super(serverHost, serverPort, browserStartCommand, browserURL);
}
public String doCommand(String commandName, String[] args) {
StringBuffer sb = new StringBuffer();
sb.append("|" + commandName + "|");
if (args!=null) {
for (String arg : args) {
sb.append(arg + "|");
}
if (args.length<2) {
sb.append(" |");
}
} else {
sb.append(" | |");
}
System.out.println(sb.toString());
// or log it where you want
return super.doCommand(commandName, args);
}
}
And
import com.thoughtworks.selenium.DefaultSelenium;
public class ExtSelenium extends DefaultSelenium {
public ExtSelenium(String serverHost, int serverPort,
String browserStartCommand, String browserURL) {
super(new ExtHttpCommandProcessor(serverHost, serverPort, browserStartCommand, browserURL));
}
}
Then I would extend SeleneseTestCase for use as the base in my tests:
import com.thoughtworks.selenium.SeleneseTestCase;
public class ExSeleneseTestCase extends SeleneseTestCase {
public void setUp(String url, String browserString) throws Exception {
int port = 4444;
if (url==null) {
url = "http://localhost:" + port;
}
selenium = new ExtSelenium("localhost", port, browserString, url);
selenium.start();
selenium.setContext(this.getClass().getSimpleName() + "." + getName());
}
}
The output of such test will look like:
|getNewBrowserSession|*iexplore|http://localhost:8080/|
|setContext|SimpleTest.testNew| |
|open|/webapp/test.html| |
|isTextPresent|Sample text| |
|click|sampleLink| |
|waitForPageToLoad|10000| |
|testComplete| | |
This solution will not log verifys and asserts so they may also be overrided in ExSeleneseTestCase to produce some trace.

You could also go the other way, which is probably easier: save the (partial) selenese HTML files when you generate them, and from the perl/java/... code, parse the files and execute the lines using doCommand. That way, you don't have to reconstruct the asserts/verify statements, because they weren't lost in the first place.

How to Take Screenshot when TestNG Assert fails?

String Actualvalue= d.findElement(By.xpath("//[#id=\"wrapper\"]/main/div[2]/div/div[1]/div/div[1]/div[2]/div/table/tbody/tr[1]/td[1]/a")).getText();
Assert.assertEquals(Actualvalue, "jumlga");
captureScreen(d, "Fail");
The assert should not be put before your capture screen. Because it will immediately shutdown the test process so your code
captureScreen(d, "Fail");
will be not reachable
This is how i usually do:
boolean result = false;
try {
// do stuff here
result = true;
} catch(Exception_class_Name ex) {
// code to handle error and capture screen shot
captureScreen(d, "Fail");
}
# then using assert
Assert.assertEquals(result, true);
1.
A good solution will be is to use a report framework like allure-reports.
Read here:allure-reports
2.
We don't our tests to be ugly by adding try catch in every test so we will use Listeners which are using an annotations system to "Listen" to our tests and act accordingly.
Example:
public class listeners extends commonOps implements ITestListener {
public void onTestFailure(ITestResult iTestResult) {
System.out.println("------------------ Starting Test: " + iTestResult.getName() + " Failed ------------------");
if (platform.equalsIgnoreCase("web"))
saveScreenshot();
}
}
Please note I only used the relevant method to your question and I suggest you read here:
TestNG Listeners
Now we will want to take a screenshot built in method by allure-reports every time a test fails so will add this method inside our listeners class
Example:
#Attachment(value = "Page Screen-Shot", type = "image/png")
public byte[] saveScreenshot(){
return ((TakesScreenshot)driver).getScreenshotAs(OutputType.BYTES);
}
Test example
#Listeners(listeners.class)
public class myTest extends commonOps {
#Test(description = "Test01: Add numbers and verify")
#Description("Test Description: Using Allure reports annotations")
public void test01_myFirstTest(){
Assert.assertEquals(result, true)
}
}
Note we're using at the beginning of the class an annotation of #Listeners(listeners.class) which allows our listeners to listen to our test, please mind the (listeners.class) can be any class you named your listeners.
The #Description is related to allure-reports and as the code snip suggests you can add additional info about the test.
Finally, our Assert.assertEquals(result, true) will take a screen shot in case the assertion fails because we enabled our listener.class to it.

Fitnesse wiki unable to call selenium method correctly

I am trying to write a simple fixture that opens the browser and navigates to www.google.com. When I run the wiki page, it passes with all green, but the browser never opens up (I don't think the method even gets called by the wiki). Can someone take a look at my fixture and wiki to see what I am doing wrong? Many thanks in advance,
Here is the Wiki -
!|SeleniumFitness|
|URL |navigateToSite?|
|http://www.google.com| |
After Running -
!|SeleniumFitnesse| java.lang.NoSuchMethodError: org.openqa.selenium.remote.service.DriverCommandExecutor.<init>(Lorg/openqa/selenium/remote/service/DriverService;Ljava/util/Map;)V
|URL |The instance decisionTable_4.setURL. does not exist|navigateToSite?
|http://www.google.com|!The instance decisionTable_4.navigateToSite. does not exist |
Here is the Fixture -
package FitNesseConcept.fitNesse;
import java.util.Properties;
import org.junit.BeforeClass;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeMethod;
//import com.google.common.base.Preconditions.*;
//import com.google.common.collect.Lists;
import fit.ColumnFixture;
public class SeleniumFitnesse extends ColumnFixture {
public static ChromeDriver driver = null;
private String navigateToSite = "";
public String URL = "";
public SeleniumFitnesse() {
Properties props = System.getProperties();
props.setProperty("webdriver.chrome.driver", "/home/ninad/eclipse-workspace/chromedriver");
driver = new ChromeDriver();
}
// SET-GET Methods
public String getURL() {
return URL;
}
public void setURL(String uRL) {
URL = uRL;
}
public String getNavigateToSite() {
return navigateToSite;
}
public void setNavigateToSite(String navigateToSite) {
this.navigateToSite = navigateToSite;
}
// Navigate to URL
public void navigateToSite() throws Throwable {
System.out.println("Navigating to Website");
try {
driver.navigate().to(URL);
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
You are getting some good recommendations as comments - but to answer your question directly, for an old-style ColumnFixture, which is what you have written, the method "navigateToSite" is indeed not going to be called.
These styles of fixtures are not often used anymore, Slim is preferred, and your fitnesse instance in its documentation will show you how to use Slim style. However, for a column fixture as you have written, if you want a method to be called it needs to be a "?" following name of the method in the header row.
See basic docs for column fixture:
http://fitnesse.org/FitNesse.UserGuide.FixtureGallery.BasicFitFixtures.ColumnFixture
You are mis-using column fixture, even granted the old style though. Column fixture's pattern is "here is a series of columns that represent inputs, now here is a method call I want to make to get the output and check result". Navigating a website does not often fit that pattern. In old style fitnesse it would probably be approached by an ActionFixture:
http://fitnesse.org/FitNesse.UserGuide.FixtureGallery.BasicFitFixtures.ActionFixture
In the newer Slim style, a good fit for navigation and checking where you are would be a Scenario Table.
http://www.fitnesse.org/FitNesse.UserGuide.WritingAcceptanceTests.SliM.ScenarioTable
In general doing WebDriver / Selenium tests through a wiki is worth extra thought as to whether it's your best medium. Fitnesse is really designed to be a collaborative tool for documenting and verifying business requirements, directly against source code.
Here's an example of how to do with a ColumnFixture, although again ColumnFixture not exactly appropriate:
|url|navigateToUrl?|
|www.google.com| |
java class:
public String url;
public void navigateToUrl() {
}
You could return an "OK" if it navigates alright, or return the title of the page as opposed to void if you wanted.

Setting up selenium webdriver for parallel execution

I am trying to execute a large suite of selenium tests via xUnit console runner in parallel.
These have executed and I see 3 chrome windows open, however the first send key commands simply executes 3 times to one window, resulting in test failure.
I have registered my driver in an objectcontainer before each scenario as below:
[Binding]
public class WebDriverSupport
{
private readonly IObjectContainer _objectContainer;
public WebDriverSupport(IObjectContainer objectContainer)
{
_objectContainer = objectContainer;
}
[BeforeScenario]
public void InitializeWebDriver()
{
var driver = GetWebDriverFromAppConfig();
_objectContainer.RegisterInstanceAs<IWebDriver>(driver);
}
And then call the driver in my specflow step defintions as:
_driver = (IWebDriver)ScenarioContext.Current.GetBindingInstance(typeof(IWebDriver));
ScenarioContext.Current.Add("Driver", _driver);
However this has made no difference and it seems as if my tests are trying to execute all commands to one driver.
Can anyone advise where I have gone wrong ?
You shouldn't be using ScenarioContext.Current in a parallel execution context. If you're injecting the driver through _objectContainer.RegisterInstanceAs you will receive it through constructor injection in your steps class' constructor, like so:
public MyScenarioSteps(IWebDriver driver)
{
_driver = driver;
}
More info:
https://github.com/techtalk/SpecFlow/wiki/Parallel-Execution#thread-safe-scenariocontext-featurecontext-and-scenariostepcontext
https://github.com/techtalk/SpecFlow/wiki/Context-Injection
In my opinion this is horribly messy.
This might not be an answer, but is too big for a comment.
why are you using the IObjectContainer if you are just getting it from the current scenario context and not injecting it via the DI mechanism? I would try this:
[Binding]
public class WebDriverSupport
{
[BeforeScenario]
public void InitializeWebDriver()
{
var driver = GetWebDriverFromAppConfig();
ScenarioContext.Current.Add("Driver",driver);
}
}
then in your steps:
_driver = (IWebDriver)ScenarioContext.Current.Get("Driver");
As long as GetWebDriverFromAppConfig returns a new instance you should be ok...

Infrom Selenium that feature file starts \ ends

I have to make some operations when a Feature file starts or ends.
But I didn't find any way that Selenium can know it.
Meanwhile I use a specific hook tag to catch the beginning and another one to catch the end. But Is there a way to know it in Selenium code?
You can use before and after hook to perform some actions, you can add extra tag to your cucumber scenario and check it by scenario.getSourceTagNames(). see the example below:
#Before
public void setUpScenario(Scenario scenario) {
List<String> tags = scenario.getSourceTagNames();
if (tags.contains(scenario_specific_tag)) {
System.out.println("Before your scenario running ...." );
}
}
#After
public void endUpScenario(Scenario scenario) {
List<String> tags = scenario.getSourceTagNames();
if (tags.contains(scenario_specific_tag)) {
System.out.println("After your scenario ...." );
}
}

Is it possible to start few seleniums for one selenium server?

Is this valid code?
selenium = new DefaultSelenium("localhost", 4444, "*iehta",
"http://www.google.com/");
selenium.start();
...
selenium.stop();
...
selenium.start();
...
selenium.stop();
There's nothing wrong with having multiple browsers open (what you call "seleniums"). In fact, it's the only way you can test certain applications. Imagine an application that has an administrative UI and an end-user UI, where you make changes on the admin side and verify their effects on the user side. You can either write your test to jump back and forth between the two on the same browser session, or you can open two browsers, one for each aspect of the application. The former is the usual technique, but the latter is much cleaner.
And why do you think it shouldn't be safe? unless it works ok it's fine, If it doesn't than recreate the DefaultSelenium object again, it won't slow down your code anyway
You should usually keep start() and stop() as you set up and tear down methods. While using TestNG you can annonate then with #BeforeClass and #AfterClass annonations. Hence browser would be launched and shut down only before and after a test method in a class.
b/w did you support Selenium Proposal on area51 - http://area51.stackexchange.com/proposals/4693/selenium
This proposal is backed by SeleniumHQ and we need more users to commit to it to make it see day of light.
That was my fault.
Unexpected behaviour caused by this code and occurs because I stop selenium two times (selenium object never become null):
public class SeleniumController {
private static Selenium selenium;
public static Selenium startNewSelenium(){
// if already exists stop it and replace with new one
if(selenium != null){
selenium.stop();
}
selenium = createNewSelenium(getCurContext());
return selenium;
}
public static void stopSelenium() {
if(selenium != null){
selenium.stop();
}
}
private static Selenium createNewSelenium(TestContext testContext){
TestProperties testProps = new TestProperties(testContext);
ExtendedSelenium selenium = new ExtendedSelenium("localhost", RemoteControlConfiguration.DEFAULT_PORT,
testProps.getBrowser(), testProps.getServerUrl());
selenium.start();
selenium.useXpathLibrary("javascript-xpath");
selenium.allowNativeXpath("false");
return selenium;
}
}
The correct class code is:
public class SeleniumController {
private static Selenium selenium;
public static Selenium startNewSelenium(){
// if already exists stop it and replace with new one
stopSelenium();
selenium = createNewSelenium(getCurContext());
return selenium;
}
public static void stopSelenium() {
if(selenium != null){
selenium.stop();
selenium = null;
}
}
private static Selenium createNewSelenium(TestContext testContext){
TestProperties testProps = new TestProperties(testContext);
ExtendedSelenium selenium = new ExtendedSelenium("localhost", RemoteControlConfiguration.DEFAULT_PORT,
testProps.getBrowser(), testProps.getServerUrl());
selenium.start();
selenium.useXpathLibrary("javascript-xpath");
selenium.allowNativeXpath("false");
return selenium;
}
}
