testng.xml does not execute all #Test annotation within the class - selenium

Question

I'm trying to run all tests in the project using testng.xml I have 7 #Test method under one class. I used data provider for 2 test method and 5 #test method execute without data provider.
When I execute a class it executes only 1st #test method(test1).
I used dependsonmethods also but it is not working out for me.
**#Test class:**
public class regressionTest{
#DataProvider
public Object[][] getCardTestData() {
return TestUtil.getTestData(Constants.test1data);
}
#DataProvider
public Object[][] getCardTestDataNeg() {
return TestUtil.getTestData(Constants.test2data);
}
#Test(priority = 1,dataProvider = "getCardTestData", enabled = true){
public void test1{
}
}
#Test( priority = 2,dataProvider = "getCardTestDataNeg", enabled = true){
public void test2{
}
}
#Test( priority = 3, enabled = true){
public void test3{
}
}
#Test( priority = 4, enabled = true){
public void test4{
}
}
#Test( priority = 5, enabled = true){
public void test5{
}
}
#Test( priority = 6, enabled = true){
public void test6{
}
}
#Test( priority = 7, enabled = true){
public void test7{
}
}
}
**Testng.xml:**
<suite name="Automation Test Suite : Regression">
parameter name="environment" value="qa" />
<test name="Automation Test Cases : Regression" preserve-order="true">
<classes>
<class name="com.regressionTest"></class>
</test>
</suite>
