BaseTest.java
@

BeforeSuite(alwaysRun = true)
    @Parameters(value = "platformVersion")
    public void initSuite(ITestContext context, @Optional String platformVersion) {
        if (Objects.isNull(platformVersion) || (!platformVersion.isEmpty() && !platformVersion.isBlank())) // Here I am only getting platformVersion 14 for both the suites.
            System.out.println("platformVersion: " + platformVersion);
        else
            System.out.println("Platform version not provided");

    }

TestClass.java extending BaseTest.java

    @Test
public void test1(){
    System.out.println("This is test 1");
}

@Test
public void test2(){
    System.out.println("This is test 2");
}

In the @BeforeSuite method, it should give two different values for two suites but it is giving only one value for both suites.

I need clarification on this.
