How to fix VersionOne.Parsing.MismatchedCharException !

Are you irritated because of VersionOne.Parsing.MismatchedCharException while accessing version one restful API & using where clause. 



CAUSES

Due to the use of the special character in version1 restful endpoint, this error is common. 
The 'where' clauses in a rest-1.v1 query or query.v1 query only support ASCII. So any character which is non-ascii or Unicode will result in the this error. 

SOLUTION


The 'with' clause should be used by default to avoid unsupported character issues.

It should look something like this -

Scopes.Name=$name&with=$name= XXXXX: XXXXX

Install Jenkins with Docker file & preinstalled plugins. [Copy existing .jpi/.hpi file to docker image.]


Create a new file with name as Dockefile and add the below content.

FROM jenkins/jenkins:lts
USER root
MAINTAINER diehardtechy@gmail.com


if you want to copy any existing .hpi/.jpi file in your docker image, please add the below command in Dockerfile (Eg. If we want to copy perforce.jpi plugin from local machine to docker image )

COPY perforce.jpi /var/jenkins_home/plugins/



If you want Jenkins to preinstall plugins create a plugins.txt file with below content.

pluginid : version_info (For example if you want to install notification plugin with 1.13 version, we need to specify it as below, if we don’t pass version info, it will take the latest version)

notification:1.13 
ws-cleanup:0.34 
mask-passwords:2.12.0


Content of the plugins.txt file looks like as follow.






to copy the plugins.txt file to docker image, add the below command in Dockerfile.

Java 8 provides many useful classes and methods under Date Time API. Below code snippet checks if the date is a valid future date. 



        /**
  * DateTime function which checks for the valid future date.
  * 
  * @author ajain5
  * @param futureDate
  *            : in dd-mm-yyyy or dd/mm/yyyy format
  * @return true if futureDate isAfter currentDate
  */
 public boolean isValidFutureDate(String futureDate) {
  String date[] = futureDate.split("[\\/-]");
  int day = Integer.parseInt(date[0]);
  int month = Integer.parseInt(date[1]);
  int year = Integer.parseInt(date[2]);

  LocalDate today = LocalDate.now();
  return today.isBefore(LocalDate.of(year, month, day));

 }


You can test the above code using below driver program. 


System.out.println(new Ti().isValidFutureDate(args[0]));

Response after running the above program :


Current date : 22-01-2019

What is the best way to check element not present in webpage using selenium webdriver ?


Best Way of checking element not present in webpage using selenium webdriver ?


Often encountered a situation where you have to verify an element is not present in the web page. 

using 


try {

        driver.findElement(locatorKey);

        Assert.assertTrue(false);

    } catch (org.openqa.selenium.NoSuchElementException e) {

        Assert.assertTrue(true);

    }

 


is not a right approach. Because this is layman way of asserting absence of web element.

As per selenium documantaion, best way to check if element is not present is using findElements and then asseting on the size of the list returned. 

findElements does not throw any exception in case if an element is not present. Asserting on 0 length is more appropriate for absence of an element.
