[TIPS] Selenium Implicit Wait - Turn ON and OFF

While automating web application Selenium Webdriver Implicit wait is applied to all findElement and findElements keyword till the element is visible. But in some case we need to check if fields visibility immediately on performing some actions. So why to wait for default implicit wait of 15 or 30 seconds.

Here is the simple tip to override Implicit default wait time by Turning OFF the implicit wait while performing action and validating field visibility. Below Java code snippet will be helpful -

 public void turnOFFImplicitWait(Webdriver driver)  {  
   driver.manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);  
 }  

After verifying the step turn ON default implicit wait as below -

 public void turnONImplicitWait(Webdriver driver)  {  
   driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);  
 }

Find text in table without table iteration

Normally we follow the approach of iterating table, find the required text and perform some operation on same row. This approach is fast for small table but when it comes to very large table iteration will be slow enough.

Instead without iterating the table find the text using xpath and perform operation on same row.

Let take an example:

From above table we want 'Travel' time (column = 7) of particular train from 'Train No' (column=1).

String travelTime = driver.findElement(
By.xpath("//table[@id='trainInfo']/tbody/tr/td[text()='19215']/../td[7]")).getText();

OUTPUT:
Travel time: 15.35

[ERROR]How to resolve "Multiple annotations found at this line" in pom.xml file?

Today while creating new project I came across below error message in POM.xml file after deleting Junit dependencies and including TestNG dependencies and worried how to solve. Luckily I found solution from my preview project.

Multiple annotations found at this line:
- ArtifactTransferException: Failure to transfer org.apache.httpcomponents:httpclient:jar:
4.5.1 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution 
will not be reattempted until the update interval of central has elapsed or updates are forced. 
Original error: Could not transfer artifact org.apache.httpcomponents:httpclient:jar:4.5.1 from/to

- ArtifactTransferException: Failure to transfer org.apache.httpcomponents:httpcore:jar:

SOLUTION:
Just include below "httpclient" dependencies solved my problem.
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.4</version>
</dependency>
