We might need to run a particular test for multiple times for retesting and also leverage parallel test with Test method.
It can also be used to load test.

//invocationCount: repeats the test for the specified numbers of time
// threadPoolSize : Will run in multiple thread pool for parallel test or
//Load test

	@Test(invocationCount = 3, threadPoolSize = 2, timeOut = 10000)
	public static void Test1() {
		System.out.println("I am in Test1 and this is invocation test. Thread Id:" + Thread.currentThread().getId()
				+ " Current Time:" + LocalTime.now());
	}

1. Passing empty string in a cell
   Sometimes we feel the need of passing null/blank value in excel to avoid the null pointer exception and we can handle this from excel sheet without having to handle from code.
   – If you want to pass empty string just type opening single quote ( ‘ ) and it will be treated as empty string for apache poi
2. Passing number as string
   If you want to pass number or decimal as string , prefix with opening single quote ( ‘ ) and it will take it as string value.
   Ex: ‘20.00 , ’29
3. Treating a null cell as blank
   We can make use of Row policy to treat a cell as blank.

1. Check npm help
   npm help <term>
2. Check npm version
   npm -v
3. List all packages installed Globally
   npm -g list
4. List all packages installed for user
   npm list
5. Check for the specific package Globally
   npm list -g grunt
6. Check for the specific package for user
   npm list grunt
7. Check versions of all installed modules without dependencies
   npm list –depth=0 (for locally)
   npm list -g –depth=0 (globally)
8. Install a package globally
   npm install -g chromedriver (Remove -g to install locally)
9. Update all packages in current folder
   npm update
10. To see which global packages need to be updated globally
    npm outdated -g –depth=0
11. update a particular package
    npm update -g

Please visit this awesome tutorial on Selenium IDE.

How to run selenium IDE scripts in command line:

1- Make sure npm is installed

• To check npm
  npm -g -v (if installed it will show the version)
• To install it , download it from internet and install as executable in windows

2- Make sure below node dependencies are installed, if not install

• To check for selenium-side-runner
  npm list -g selenium-side-runner
• To install
  npm install -g selenium-side-runner
• To check for chromedriver
  npm list -g chromedriver
• To install
  npm list -g chromedriver

3- Download the chromedriver exe matching to the version of the chrome browser installed in system. and place it in a folder of your choice

4- Set path to the chromedriver exe
set path=%path%;C:UsersusernameseleniumFolder

5- Once done run below command
selenium-side-runner /path/to/your-project.side

Many a times we feel the need to run our UI automation tests in headless mode ( No browser visible) .
Few advantages are:

1. Faster execution, as it does not use system resource(memory and gpu) to launch browser .
2. When we do not need to bother about browser view and do not want any distraction while running tests. (Working in local machine)

Code:

ChromeOptions options= new ChromeOptions();
//Based on your screen resolution
options.addArguments(“window-size=1400,800”); 
options.addArguments("--headless");
options.addArguments("--disable-gpu");
WebDriver driver =  new ChromeDriver(options);
driver.get("https://testapplicationurl.com");

You can also take screenshots in headless mode.

Step1: Setup using maven:
Note: Depending on the command line tool you use, you need to format the below command.
In the below example I am using GIT Bash, it accepts the multi line command as below.
If you are using windows cmd or other editor which do not support multi line, just remove backslash () and format all the steps in one single line command.

mvn archetype:generate 
-DarchetypeGroupId=com.intuit.karate 
-DarchetypeArtifactId=karate-archetype 
-DarchetypeVersion=0.9.5 
-DgroupId=com.yourcompanyname 
-DartifactId=myprojectname

Step2: Import the project in VS Code
– Open VS Code and right click in workspace- add folder to workspace
– This will import the java project

Step3: Run maven install
– Go to terminal and navigate to the newly imported folder in vs code

mvn clean install -U

– This will install all dependencies
– Also it will run default tests which comes as part of the project
– You should see build success.

Step4: Run using Maven

mvn test

Alternatively Use ZIP Release of Karate in VS Code:

When sending larger amount of data to the server it’s common to use the multipart form data technique. Rest Assured provide methods called multiPart that allows you to specify a file, byte-array, input stream or text to upload. In its simplest form you can upload a file like this:

Option 1: File (.json , .txt) without control name (Default control name: file)

given().
        multiPart(new File("/path/to/file")).
when().
        post("/upload");

Option 2: File (.json , .txt) with Control name

given().
        multiPart("controlName", new File("/path/to/file")).
when().
        post("/upload");

Option 3: File (.pdf) with Control name

given().
      multiPart("controlName", new File("/path/to/file"),"application/pdf").
when().
        post("/upload");

Option 4 : json object with Control name

given().
        multiPart("controlName", jsonObject,"application/json").
when().
        post("/upload");

Option 5 : PDF file + json object with Control name

given().
      multiPart("controlName", new File("/path/to/file"),"application/pdf").
      multiPart("controlName", jsonObject,"application/json").
when().
        post("/upload");

Ignoring NULL (optional field) while making POJO:

Option 1 : (Recommended) To add in class level
@JsonInclude(JsonInclude.Include.NON_NULL)
* This is best suitable while using Lombok and builder pattern

Option 2 : To add in Getter level
@JsonInclude(Include.NON_NULL)
* This is only suitable while using without lombok and only with builder pattern

Error: Lombok 1.18.12 does not compile well with maven compiler 3.8.1.
So downgrade lombok to 1.16.6

Note: This lombok feature is now already available java 14 as built -in feature

Sometime while working with a project , we come in a situation where we see that some files or folders are being tracked but later we do not want them to be tracked.

It might be possible that while creating .gitignore file we forgot to add those files/folders pattern.

Such examples are : target folder, custom folders lke log,report etc which we add later after we create .gitignore.

So we can tell git to stop tracking for these files for any changes made in future but still want these to remain in out local, so that we can work with them locally without any issues.
The solution is :

Step1: execute below command in git bash or command line while within the same project dir.
This will tell git that these are deleted and git will stop tracking ( Tricking git)

git rm -r --cached path_to_your_folder/
or
git rm -r --cached filename_pattern

Step2: Add those folder/file in .gitignore too.
So that in future even these files or folders being created or mistakenly added, still it will be ignored by git.

Step3: Now commit these changes and push. (1-deletion of excluded folder/file and 2-updation .gitignore)

Check this article if you want to know more about what files to ignore.

I was searching on internet for what files should I ignore while pushing it to github. I found this nice website which does all the job for you.

Simply enter OS, IDE,Language and hit enter:

https://www.gitignore.io/
