Is there any way to use Parameters with DataProvider together in Selenium ?
@Parameters({"safaf"})
@DataProvider(name="sss")
public void hhhhh (String safaf){
}

Yes, it can be done. Parameter passing in TestNG can be done two ways:
- Using
@Parametertag and you pass the value from yourtestng.xmlUseful when your dealing with simple parameter - Using
@DataProvidertag Useful if your reading values from prop file or database.
So your testng.xml will look something of this sort:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="Suite123">
<test name="test123">
<parameter name="safaf" value="blah"/>
<classes>
<class name="DataProvider123" />
</classes>
</test>
</suite>

Unfortunately, it does not work! @Parameters({"path"}) @Test(priority=2,dataProvider="db") public void description2( String path,String item) I got this error (The data provider is trying to pass 1 parameters but the method com.macys.NewTest#description2 takes 2 and TestNG is unable in inject a suitable object)!!!! anyway, Thanks for your help– osamaOct 17, 2015 at 5:29

Ok, i wasn't precise earlier. Do not use both the annotation together on @Test. Follow the below approach: ` String myParam; @BeforeClass @Parameters("test") public void one(String p1) { p1 = this.myParam; } @Test(dataProvider="dp") public void two(String p2){ } Oct 19, 2015 at 0:34

No, i was looking for something else. I've changed my code to avoid this problem.– osamaOct 22, 2015 at 4:05
DataProvider is a method in a class that returns a two dimensional an array of object (Object [ ][ ]) to the test method. The test method will be called m times in the m*n type of object array. Where m ➨ The first array m represents the number of rows that has to be repeated your test m number of times. n ➨ The second array n represents a column that is the number of parameters in the test data. This method is annotated with @DataProvider. DataProvider in TestNG
