parallel testing in junit
If we use JUNIT, we can use maven plugins to run tests in parallel.
In maven-surefire-plugin, we can specify how many threads we want to open
at the same time.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<parallel>classes</parallel> ==> you can choose classes or methods
<threadCount>5</threadCount> ==> how many browser will be launched
<includes>
<includetest1.java</include>
<includetest2.java</include>
<includetest3.java</include>
<includetest4.java</include>
</includes>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</plugin>
We also have to make some changes in Driver class. We need to use
"ThreadLocal<WebDriver> driverPool" instead of "WebDriver driver".
Because "WebDriver" generates only a single WebDriver object,
whereas "ThreadLocal<WebDriver>" generates multiple browser to run
parallel testing.
In TestNG it is very easy and efficient to perform
