Edwin Herrera How do I test code?
Hi,
I am new to apex developer and I am having issues test the code I created for one of the modules. Below is the code I am attempting to test.
public class StringArrayTest {
public static String[] generateStringArray(Integer i){
String [] tests= new List<String>();
for(Integer n=0;n<i;n++){
tests.add('test '+n);
}
return tests;
}
}
I click on run all tests and it states there are no tests. When I try to complete the challenge it tells me there is no class created.
Any help would be great.
Thank you.

Yes,you need to create a test class to test any apex class/trigger in salesforce.
Please follow the below link.You will come to know how we can create a testclass in salesforce .

Thanks!!!
Please comment if you find this helpfull.
I think the problem in your code is that Trailhead is looking for the output 'Test 1' etc, whereas your code returns 'test 1' with a lowercase t.
Changing the line
tests.add('test '+n);
to
tests.add('Test '+n);
should help!
Clicking run all tests does nothing at this point as you haven't actually written any unit tests. In Salesforce you're required to write code that tests your code - this test code is marked with an @isTest annotation and gets run when you click the button. There's definitely a module on unit testing on trailhead that's worth a run through!
Hope this helps,
Lizzy
You can refer the below test class.
@isTest public class TestStringArrayTest { @isTest static void myTest(){ List<String> stq= StringArrayTest.generateStringArray(10); } }Please comment if this helpful and mark this question as solved.Thanks.
