Step 1: Store item of the list in a List using findElements
List<WebElement> searchResultlist = Driver.driver.findElements(By.xpath("//span[@class='document-name']"));
Step 2: Use for loop to traverse in the list and verify the text using IF condition.
To make sure input by the user and text from the application are in same case, convert both the strings in UPPER case and match.
for (WebElement resultList : searchResultlist){
System.out.println(resultList.getText());
if (resultList.getText().toUpperCase().contains(DocumentNumber.toUpperCase())){
resultList.click();
break;
}
}
How to set JAVA Path in Linux machine
Run below command to install JAVA
yum install java-1.8*
Once the installation is completed, run below command to check JAVA Version.
java -version
Above command should give you the following result.
openjdk version "1.8.0_232" OpenJDK Runtime Environment (build 1.8.0_232-b09) OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)
Run below command to find the JAVA path.
find /usr/lib/jvm/java-1.8* | head -n 3
Above command should give you the following results.
/usr/lib/jvm/java-1.8.0 /usr/lib/jvm/java-1.8.0-openjdk /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64
Use last path from above result to update the bash profile.
To update the bash profile run below command.
vi .bash_profile
Update bash_profile as below.
JAVA_HOME = /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64 PATH=$PATH:$JAVA_HOME:$HOME/.local/bin:$HOME/bin
Save and Exit the bash_profile.
Refresh the bash profile using the below command.
source ~/.bash_profile
After refresh, run the following command to verify the JAVA path.
echo $JAVA_HOME
Output of the above command should be:
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64

Docker certificate signed error
$ docker ps
error during connect: Get https://192.168.99.100:2376/v1.37/containers/json: x509: certificate signed by unknown authority
Above error appears a lot in docker if any changes made in the settings. Or sometimes if system is restarted.
How to resolve this error?
I executed below steps to solve this error:
Go to your docker toolbox folder and run the below command.
@S500719W10N MINGW64 /c/Program Files/Docker Toolbox
$ docker-machine regenerate-certs default

After running the above command problem should be resolved. In case if problem still not resolved, then follow the below steps:
Use SSH to login to virtual machine:
$ docker-machine ssh default
docker@default:~$ sudo vi /var/lib/boot2docker/profile
Add a NO_PROXY setting
# replace with your oproxy environment settings
export “HTTP_PROXY=http://PROXY:PORT”
export “HTTPS_PROXY=http://PROXY:PORT”
# you can add more no_proxy with your environment.
export “NO_PROXY=192.168.99.,.local,169.254/16,.example.com,192.168.59.“
Restart docker
docker@default:~$ sudo /etc/init.d/docker restart
docker@default:~$ exit
$ docker-machine regenerate-certs default
