Soft assertions vs Hard assertions in TestNG

When hard assertion will fail Inside any test method, remaining execution of that specific test method will be aborted. Now If you wants to continue remaining test part execution even If assertion fails and also you wants to report assertion failure In testng result report then you can use testng soft assertion method.

syntax:

import org.testng.asserts.SoftAssert;
SoftAssert s_assert = new SoftAssert();
s_assert.assertEquals(actual, expected);

collect javascript errors (those coming up in the console) from firefox through java.

selenium quick tutorial

Tool Selection:

Before finalizing automation tool we should consider below points

Ease of usage

Quick Support

Technology support

Cost

Compatible with different browsers and operating systems

Selenium is open source WEB automation testing tool.

Technologies: java , c#, Ruby, Python, PHP

Browsers: ie, chrome, Firefox, opera, safari

OS: win, max, Linux, Unix

Selenium components:

IDE, RC, WebDriver 2.0, Web Driver 3.0, Grid

IDE: add-on Firefox browser. For record and play back only. With the help of user extensions, we can improve functionality. Supports conditional, iterative, regex. Tests can be parameterized using IDE

RC: (1.0 ), supports multiple browsers, supports most of the programming languages

WD: (2.0, 3.0) : eliminated drawbacks in RC ( by eliminating server ). We can make direct calls to the browser using various drivers available. Supports mobile testing

GRID: to run tests parallel on different machines at a time

Advantages:

Free and open source

Multi browser and OS support

Parallel execution

Mobile testing

IDE – record and play back for quick automation evaluation

Continuous integration support

Easy framework development (data, keyword, hybrid, POM, PF )

Support for testing, junit etc

Capabilities:

Capabilities are options that you can use to customize and configure a Browser Driver session.

Chrome:

DesiredCapabilities capabilities = DesiredCapabilities.chrome();

// Add the WebDriver proxy capability.

Proxy proxy = new Proxy();

proxy.setHttpProxy("myhttpproxy:3337");

capabilities.setCapability("proxy", proxy);

// Add ChromeDriver-specific capabilities through ChromeOptions.

ChromeOptions options = new ChromeOptions();

options.addExtensions(new File("/path/to/extension.crx"));//browser extensions

options.addArguments("start-maximized");//start chrome maximised

options.setBinary("/path/to/other/chrome/binary");// chrome.exe file path, if multiple verions available

options.addArguments("user-data-dir=/path/to/your/custom/profile");//By default, ChromeDriver will create a new //temporary profile for each session. At times you may want to set special preferences or just use a custom //profile altogether

capabilities.setCapability(ChromeOptions.CAPABILITY, options);

ChromeDriver driver = new ChromeDriver(capabilities);

--OR--

RemoteWebDriver driver = new RemoteWebDriver(

new URL("http://localhost:4444/wd/hub"), capabilities);

Internet Explorer:

Set below browser options

DesiredCapabilities capabilities = DesiredCapabilities.internetExplorer();

capabilities.setCapability(CapabilityType.BROWSER_NAME, "IE");

capabilities.setCapability(InternetExplorerDriver.

INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);

capabilities.setCapability(InternetExplorerDriver.INITIAL_BROWSER_URL, "https://testvmm6.partnersonline.com/vmm");

capabilities.internetExplorer().setCapability("ignoreProtectedModeSettings", true);

capcapabilities.setCapability("IE.binary", "C:/Program Files (x86)/Internet Explorer/iexplore.exe");

capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);

capabilities.setJavascriptEnabled(true);

capabilities.setCapability("requireWindowFocus", true);

capabilities.setCapability("enablePersistentHover", false);

System.setProperty("webdriver.ie.driver", "C:\\IEDriverServer.exe");//32 bit driver is good

WebDriver driver = newInternetExplorerDriver(capabilities);

Navigation methods:

Driver.get(“url”)

Driver.getTitle()

Driver.getCurrentURl()

Driver.getPageSource()

Driver.close()//closes current browser

Driver.quit()//closes all browsers under the driver

Driver.navigate().to(“url”)

Driver.navigate().forward()

Driver.navigate().back()

Driver.navigate().refresh()

Locators:

Common web elements are TextBox, Button, DropDown, Anchor Tag, ChecBox, Radio Button.

We can locate elements using ID, class name, Name, link text, xpath, css selector ( id, class, attribute, substring, Innter text )

ID: Driver.findElement(By.id(“myId”))

Name: Driver.findElement(By.name(“name1”))

Class: Driver.findElement(By.class(“class1”))

linkText: Driver.findElement(By.LinkText(“Help”))

Xpath: Driver.findElement(By.xpath(“//intput[@title=’sample tool tip’]”)

Tagname: Driver.findElement(By.tagName(“input”))

cssSelector: driver.findElement(By.css(‘#myId’))

FindElement vs FindElements

WebElement ele = Drive.findElement(By.id(“#myId”)) // returns only one element

List<WebElemen> list = Driver.findElements(By.tagName(“input”))// returns list of elements

Events:

Common web element interactions are

Click(), clear(), sendKeys(“”), isDispalyed(), isSelected() ( applicable for check box and Radio button ) ,getText().getAttribute(“attr”), getSize(), getLocation() ( returns X and Y co-ordinate )

Synchronization ( webDriver waits):

Implicit wait: wait is applicable for all the elements under the driver object.

Wait for all the elements maximum 10 seconds if not available by default.

If element found, skips the wait time.

Driver.manage().timeouts.implicitWait(10,TimeUnits.SECONDS)

Explicit Wait : wait is applicable for only one element under the driver object.

We can specify explicit waiting conditions for any element so that our test should pass.

Ex: wait for this element until this element is clickable , upto maximum 55 seconds.

If element found, skips the wait time.

Few expected conditions are below:

elementToBeClickable()

textToBePresentInElement()

alertsPresent()

Titles()

framToBeAvaialbeAndSwitchToIt()

Actions Class:

Helps to handle keyboard and mouse events ( ex: drag and drop, selecting items holding Control key or alt key etc )

Actions builder=new Actions(driver);

builder.moveToElement(username,150,22);

builder.sendKeys("Mahesh");

builder.perform();

Action seriesofactions=builder.moveToElement(username).click().keyDown(username,Keys.SHIFT).sendKeys(username,"hell").keyUp(username,Keys.SHIFT).doubleClick(username).contextClick(username).build();

seriesofactions.perform();

clickAndHold()

release()

contextClick()

doubleClick()

dragAndDrop(source,target)

dragAndDropBy(source,x-offset,y-offset)

keyDown(modifier_key)

keyUp(modifier_key)

moveByOffset(x-offset, y-offset)

moveToElement(toElement)

sendKeys(onElement, charSequence)

Screen capture:

If we wanted to take screen shot of current browser, here is the way

WebDriver driver = new FirefoxDriver();

driver.get("http://www.google.com/");

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);

// Now you can do whatever you need to do with it, for example copy somewhere

FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

Switch to :

Here is the code to switch to new browser and and close it and switch back to original browser.

// Store the current window handle

String winHandleBefore = driver.getWindowHandle();

// Perform the click operation that opens new window

// Switch to new window opened

for(String winHandle : driver.getWindowHandles()){

driver.switchTo().window(winHandle);

}

// Perform the actions on new window

// Close the new window, if that window no more required

driver.close();

// Switch back to original browser (first window)

driver.switchTo().window(winHandleBefore);

// Continue with original browser (first window)

Alerts:

Below is the code for accepting alert box and getting alert text

String alertText = "";

WebDriverWait wait = new WebDriverWait(driver, 5);

// This will wait for a maximum of 5 seconds, everytime wait is used

driver.findElement(By.xpath("//button[text() = \"Edit\"]")).click();//causes page to alert() something

wait.until(ExpectedConditions.alertIsPresent());

// Before you try to switch to the so given alert, he needs to be present.

Alert alert = driver.switchTo().alert();

alertText = alert.getText();

alert.accept();

return alertText;

Acceptance testing Framework: concordion

Acceptance testing Framework: concordion

“Next gen BDD”

Concordion lets you write tests in normal language use in paragraphs , tables and proper punctuations.

Tests are written in html and then instrumented with special attributes that concordion interprets to execute the test

Intro:

Concordion is a Java library that allows to bind an HTML document to methods in a Fixture - a Java class that does various binding work. When you execute that specification, it generates an HTML output of what has been tested, with errors in red and ‘test ok’ in green.

Sample Project:
