How to change chrome download path using selenium

How to change chrome download path using selenium
How to change chrome download path using selenium

We can change our chrome download folder location from chrome settings and provide our desired location, but in case of automation, we need to change our download location dynamically. Suppose we need to download a file from an application and need to verify the downloaded file is a valid file or not. We have different API or jars are available to verify the document. I will discuss this verification in my later post. First, we need to download the file in a folder and folder will be created in runtime may be based on timestamp. So you can understand download path will be different every run. 

There is the code which will set the chrome download path runtime. 


 public WebDriver driver;  
 System.setProperty("webdriver.chrome.driver", driverPath+"chromedriver.exe");  
 HashMap<String, Object> chromePrefs = new HashMap<String, Object>();  
 chromePrefs.put("profile.default_content_settings.popups", 0);  
 chromePrefs.put("download.default_directory", downloadFilepath);  
 ChromeOptions options = new ChromeOptions();  
 options.setExperimentalOption("prefs", chromePrefs);  
 options.addArguments("--disable-notifications");  
 DesiredCapabilities cap = DesiredCapabilities.chrome();  
 cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);  
 cap.setCapability(ChromeOptions.CAPABILITY, options);  
 System.setProperty("webdriver.chrome.driver", driverPath+"chromedriver.exe");  
 driver = new ChromeDriver(options);  

Hope it will solve your problem. 

How to highlight elements in WebDriver during runtime

How to highlight elements in WebDriver during runtime

In web automation-testing, element highlighter plays a very important role. It helps to track the exact step to be performed.  UFT/QTP like testing tool is capable to highlight an element in run time because you will get this feature inbuilt with this tool. In Selenium there is no such feature available so we need to write our own code to highlight element.

  
Highlighting element is also useful for debugging the code.One way to know steps being performed in the browser is to highlight the web page elements.

The core to use "JavaScriptExecutor" to inject javascript in your application and change the CSS for the element, like create a border for the element. 

Sample code 
 JavascriptExecutor js=(JavascriptExecutor)driver;   
 js.executeScript("arguments[0].style.border='4px groove red'", Element);  

Explanation  

Arguments[0].style.border:- this script is injecting the CSS style tag into the element and making its border settings with a 4px wide red line with groove look.

Element: - This is the element around which border will be drawn.

I am creating a method which could be reusable for highlighting the test element. 

Element Highlight method 


 public void HighlightElement(WebDriver driver, WebElement elm){  
           try{  
                JavascriptExecutor js=(JavascriptExecutor)driver;   
                js.executeScript("arguments[0].style.border='4px groove red'", elm);  
          Thread.sleep(1000);  
          js.executeScript("arguments[0].style.border=''", elm);  
           }catch(Exception e){  
                System.out.println(e);  
           }  
      }px groove red'", email);

How to use chrome headless using selenium

How to use chrome headless using selenium

How to use chrome headless using selenium  


A headless browser is a kind of web browser which has no user interface, In other words,  a browser, that access web pages but doesn’t show them to any human being. They’re actually used to provide the content of web pages to other programs. 



Why is that useful?



A headless browser is a great tool for automated testing and server environments where you don't need a visible UI shell. For example, you may want to run some tests against a real web page, create a PDF of it, or just inspect how the browser renders an URL.

Now Chrome also supports headless feature from version 59 .  

Right now, Selenium opens a full instance of Chrome. In other words, it's an automated solution but not completely headless. However, Selenium could use --headless in the future.


There are few bugs  in new chrome driver so we need to use 2 chromeOptions to use headless Chrome in selenium  

Here is code for chrome headless  in windows system 

 import org.junit.Assert;  
 import org.junit.Test;  
 import org.openqa.selenium.By;  
 import org.openqa.selenium.WebDriver;  
 import org.openqa.selenium.chrome.ChromeDriver;  
 import org.openqa.selenium.chrome.ChromeOptions;  
 import org.openqa.selenium.support.ui.ExpectedConditions;  
 import org.openqa.selenium.support.ui.WebDriverWait;  
 import java.io.IOException;  
 public class HeadlessChrome  
 {  
  @Test  
  public void createChromeDriverHeadless() throws IOException  
  {  
    ChromeOptions chromeOptions = new ChromeOptions();  
    System.setProperty("webdriver.chrome.driver", "C:\\Users\\anjan\\Desktop\\cucmber\\chromedriver_win32\\chromedriver.exe");  
    chromeOptions.addArguments("--headless");  
    chromeOptions.addArguments("--disable-gpu");  
    WebDriver Driver = new ChromeDriver(chromeOptions);  
    Driver.navigate().to("https://www.facebook.com");  
    WebDriverWait waitForUsername = new WebDriverWait(Driver, 5000);  
    waitForUsername.until(ExpectedConditions.visibilityOfElementLocated(By.id("email")));  
    Driver.findElement(By.id("email")).sendKeys("tomsmith");  
    Driver.findElement(By.id("loginbutton")).click();  
    WebDriverWait waitForError = new WebDriverWait(Driver, 5000);  
    waitForError.until(ExpectedConditions.visibilityOfElementLocated(By.id("email")));  
    Assert.assertTrue(Driver.findElement(By.id("loginbutton")).getText().contains("Log In"));  
    Driver.quit();  
  }  
 }  

How to create maven project in eclipse for selenium



how to create maven project in eclipse for selenium

How to create maven project in eclipse for selenium

In my earlier post I have discussed about maven tool on automation front.  I have also discussed about whats is POM and why we use maven tool for java project .  In this post I will create one sample selenium project using maven. Before creating the maven project we need to download and install maven.  I am assuming you  have JAVA and eclipse IDE installed in your machine.

Prerequisite 

  1. Download Maven LINK.
  2. Install maven .
  3. Add M2_HOME and MAVEN_HOME in the Windows environment, and point it to your Maven folder.
  4. Add Path
  5. Verify
  6. Install maven plugin in your eclipse.  
1. Download Maven

You can download maven from the below link.  
2. Install maven .

There is no installation file. You just need to download the archive file and extract in tour hard drive. Assuming you have extract the folder in C:\Program Files\Apache\maven

maven folder after unzip


3. Add M2_HOME and MAVEN_HOME

Add M2_HOME and MAVEN_HOME variable in windows environment.

M2_HOME should be C:\Program Files\Apache\maven
MAVEN_HOME should be C:\Program Files\Apache\maven


4.  Add Path
You need to Update PATH variable, append Maven bin folder – %M2_HOME%\bin, so that you can run the Maven’s command everywhere.

5. Verify

Run the below command to know that maven installed and configured in your system properly or not. If you see the version and maven home after executing the command it means maven configured properly. 

Maven command 

mvn –version in the command prompt/cmd

6. Install maven plugin in your eclipse. 

You need to download eclipse maven plugin from eclipse marketplace.
Maven plugin for eclipse

Or if you really don't want to do this above mentioned steps to configure maven in your system there is another simple way to solve this problem.You just need to download maven enabled eclipse from the eclipse website. Here is the link below for eclipse luna with eclipse integration .


Till now we have configured the maven environment.  Now we will create selenium project with maven 

Step 1:  Create maven project from eclipse IDE 

Go to File -> Project -> Maven -> Maven Project 

Next screen will ask for your project location where you want to create the project.  You can use Default Workspace location. 


Step 2:  Select Archetype 

 In the next screen, It will ask you to select an Archetype. Depending on the type of project that you are working, you need to choose the archetype


Step 3:  Enter a group id for the artifact

Now you need to enter a group id for the artifact, artifact id ,version and package,
We will input as shown in the below image. Version number will be by default 0.0.1-SNAPSHOT


Step 4: Finish step

After clicking finish button the maven project will be created with maven structure. It will create one sample POM also.

Sample POM look like this

Step 4: Edit POM file and add selenium dependency 

Copy the selenium dependency XML from maven central. or you can also get the XML from selenium org web site


  1. selenium website  -  LINK http://docs.seleniumhq.org/download/maven.jsp


    2. maven central   - LINK


Edit the POM XML file for the project and add the selenium dependency 



Step 6: Save the project using CTRL+S

Once you save the project it maven start building the project. Means maven start pulling all required dependency  from the maven central.

You can build the project using build maven command. you can set the goal as compile.


Step 7:  Navigate to src/test/java 

If you navigate to src/test/java folder , you will see there is class call AppTest . You can use this call for writing test case or you can create different class file per your requirement. 

I have created separate  class file called "TestCode" under src/test/java folder. I am using junit for writing test.  If you look into the POM file , you will see junit is already added in the dependency.  If you observe junit is not added in your POM file then you need to add the dependency for junit. 



Step 8:  Run the Junit test

Run the test in junit you will see chrome will open and navigate to facebook page . In my previous post I have mentioned how to open chrome in selenium.

Basic of maven tool on Automation front



Basic of maven tool on Automation front


A build tool is a tool that automates everything related to building the software project. Maven, is an innovative software project management tool, provide new concept of a project object model(POM) file to manage project's build , dependency and documentation, this session is to target the beginners in helping them understand the basic of maven tool on Automation front

 Why Automation Build Tool 

  1. Accelerate the compile and link processing.
  2. It will minimize the human errors while building a software.
  3. Reduce redundant tasks.
Maven is a 
  1. Building tool.
  2. Dependency management tool
  3. Project management tool  
Core concept in Maven depends on following points 
  1. Dependencies and repositories 
  2. Build Life Cycle 
  3. Phases
What is Dependencies

Dependencies are required jars which are required to build the project.
Include all Jars and plugins in project.

Maven Repository 

3 types of maven repository 
  1. Local Repository : Local repository is a folder location in development machine and it gets crated when you run any maven command for the first time. (By default folder name is .m2)
  2. Central Repository : Maven central repository is repository provided by Maven community. It contains a large number of commonly used libraries.  http://repo1.maven.org/maven2/
  3. Remote repository :Some time maven dose not find required file in central and due to this build process gets failed.  To overcome this problem Maven provides concept of Remote Repository which is developer's own custom repository containing required libraries or other project jars.  
Sample POM for Remote repository 

how to use Remote repository in POM

Build Life Cycle

Maven has mainly 3 build in life cycles
  1. Clean
  2. Site
  3. Default
What is POM 
A Project Object Model or POM is the fundamental unit of work in Maven. It is an XML file that contains information about the project and configuration details used by Maven to build the project
  • Maven reads POM file to build the project. 
  • Specifies project information, plugins, goals, dependencies and profiles. 
Sample POM 


Sample pom for cucumber


Sample project structure for Maven project  


maven project sample

In my next post I'll explain how to configure MAVEN project and sample selenium maven project. 

Cucumber scenario outline with examples


Cucumber scenario outline with examples


Scenario outline basically replace the value with the datatable value.  Here each row of the data table consider as a new scenario.  For example suppose I want to login into the www.facebook.com site.  As of now we have execute only one scenario. We have provided username and password for login into the facebook site.  If you closely look into the site you can see there 3 different ways to login into the application.

  • We cant provide email id and password.
  • We can provide phone number and password.
  • We can provide user name and password. 
Now we can achieve above mentioned scenarios in 3 different scenario with 3 different input type 

Scenario 1:

Feature: Login Application
  As a user
  I want to login to the application

  Scenario: Valid user email id and password
    Given I launch the url "https://www.fb.com"
    When I enter password and email
    And I click on login button
    Then I should see the login page

Scenario 2:


Feature: Login Application
  As a user
  I want to login to the application

  Scenario: Valid user phone number and password
    Given I launch the url "https://www.fb.com"
    When I enter password and phone no.
    And I click on login button
    Then I should see the login page

Scenario 3:

Feature: Login Application
  As a user
  I wa
  Scenario: Valid user name and password
    Given I launch the url "https://www.fb.com"
    When I enter password and username
    And I click on login button
    Then I should see the login pagent to login to the application

Here you can see the scenario statements are same for all there scenario, only difference is that the parameter(user name / phone number/ email id). Here is the scenario outline feature comes into the picture. 

We can design this login feature in such a way where  scenario will be only one but test data will be 3 and the scenario will be execute 3 times. 

Till now we have used Scenario keyword in feature file but iteration purpose we should use Scenario Outline instead of Scenario.


Feature file : ScenarioOutline.feature

Feature: Login Application
  As a user
  I want to login to the application

  Scenario Outline: Valid user name and password
    Given I launch the url "https://www.fb.com"
    When I provide "<username>" and "<password>"
    And I click on login button
    Then I should see the login page

    Examples: 
      | username          | password |
      |        987654210 | [email protected] |
      | username1          | [email protected] |

Here the Examples annotation  describe the range of iteration , means how many times the test case will execute. In this example the test case will execute 3 times.
