I Have a suite of suites as below. These suites when executed individually, the @BeforeSuite method present in parent class of the included tests runs as expected. But when I combine the suites in one parent suite as below, the @BeforeSuite executes only once.

Is this an expected behavior? Or should the BeforeSuite method execute once for each of the suite files?

```
<?xml version="1.0" encoding="UTF-8"?>
<suite name="Parent Regression Suite">
    <suite-files>
           <suite-file path="./testng_xmls/LoginTests.xml" ></suite-file>
           <suite-file path="./testng_xmls/Info.xml" ></suite-file>
    </suite-files>
</suite>

```
