Recently I faced the issue in Eclipse were my CTRL+Space (Content Assistant) was not working. Everytime I press CTRL+Space eclipse shows nothing. Finally I managed to find the solution by changing the Preferences of my Eclipse editor.

[TIPS] Extract digit or non-digit from String using JAVA

Single line command to extract digit from a String
Eg. text = All (68)

text = text.replaceAll("\\D+", "");

Output - text = 68

Now \D represent the digit character i.e. 68
Also \d represent the non-digit character i.e. All ()
+ represent one or more time

[TIPS] Wait for Page Load in Selenium Webdriver

Selenium WebDriver supports implicit wait (applies on findElement and findElements) and explicit wait (works with some explicit condition specified by automation tester on page element. Check Selenium 2 library for more details).

Using selenium WebDriver with Java script we can wait for Page load condition.

I created below method under my UIAction class which I re-used.
public boolean waitForPageLoad(long seconds) {
try {
new WebDriverWait(driver, seconds).until(new ExpectedCondition<Boolean>() {
@Override
public Boolean apply(WebDriver wdriver) {
return ((JavascriptExecutor) driver).executeScript("return document.readystate").equals("complete");
}
});
return true;
} catch (Exception e) {
System.out.println("Method waitForPageLoad: Exception " + e.getMessage());
return false;
}
}

Now above code executed JavaScript code "document.readystate" which return following 5 string values:
uninitialized - page loading not yet started
loading - page loding inprogress
loaded - page loaded
interactive - user can intereact with fields
complete - page fully loaded

Useful Unix or Linux command on single post

Get process id of all the running program on Unix or Linux system.
ps ax | grep java

OUTPUT:
22491 pts/0    S+     0:00 grep --color=auto java
27209 ?        S      0:00 sudo nohup java
27210 ?        Sl     2:58 java

Kill process using process id (PDID) in unix or linux:
sudo kill -9 27210

Below command will fetch count of files in a particular director in Unix or Linux system?


ls -l | grep -v ^l | wc -l

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:
