TestNG:Cannot find class in classpath, testng.xml

This is my testng.xml file, i named it differently, but it should still work:

  <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://ift.tt/19x2mI9" >

<suite name="TEST_LINKS">

<test name="TECT на подбор спеца">
    <classes>
       <class name="Podbor_specalista_url_click_test" />
    </classes>
  </test>

  <test name="TECT на клик блога">
    <classes>
       <class name="Blog_url_click_test" />
    </classes>
  </test>

</suite>
