How to priortized the test cases in maven run? - maven

Question

I have 3 test cases i.e. 1 2 3. How will i give priority as 2 1 3 while executing maven command.

Answer 1

I assume you want to do it because you need some prerequisition prior the test can be run. You can do it by #Before Annotation prior the actual testcase, or you can call other tests from the test method.
Say, testClient() test will test and verify that new client can be added to the system. Then you can do this:
#Test
public void testWithdrawal(){
testClient(); // i need client existing before the test can be run
// ... do something else
}
In that case you have assured that prerequisites are fullfilled and dont have to worry much about the testcases order
EDIT
I think I understand your needs, because I am in quite similar situation. How I solved it:
For create I have special class, which can create me a data and return needed data. So, i have something like:
#Test
public void testShare(){
CreateTests create = new CreateTests; //This will just initialize the object
create.testCreate(); // this method can contain steps needed to create
String justCreatedEntity = create.getEntity(); // just example how you can use the just created entity in further tests
}
And my class to solve the create is something like this
public class CreateTests{
private static String entity; //static because i dont want it to be flushed when test ends
public void testCreate() throws Exception{
WebDriverBackedSelenium selenium = new WebDriverBackedSelenium(driver, "baseURL");
selenium.... // All the selenium stuff
setEntity(selenium.getText("id=mainForm.createdentity"));
}
public void setEntity(String ent){
this.entity = ent;
}
public String getEntity(){
return entity;
}
Its just an outline - but basically, I have these "crucial" entities as standalone objects, called by the test class. Inside test, i verify everything throgh getters. Like:
Assert.assertNotNull(create.getAuctionID(),"New Entity is NULL!" );

You can run mvn test with options to specify a single test, or multiple tests. The order they are run in is the order specified on the command line.
Reference is here: http://maven.apache.org/plugins/maven-surefire-plugin/examples/single-test.html
Note that Java suggests that the good unit testing practice of tests not requiring to be run in order and test to not rely on each other:
