Setting up spring-test in ant ivy project

I'm new to ant ivy project, I'm trying to setup spring-test for the ant project. I couldn't find any doc online.

<dependency org="org.springframework" name="spring-test" rev="5.1.9.RELEASE"/>

I'm stuck with the ant task defined in build.xml

https://docs.spring.io/spring/docs/current/spring-framework-reference/testing.html#testing

Basically, I'm writing all the test cases in the package and I want all the test cases to be executed when I run ant test command.

Some help will be appreciated.
