Data provider problems
Reports references to data provider methods that do not exist or are not accessible.
Locating this inspection
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
MalformedDataProvider- Via Settings dialog
Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
Example:
public class InstanceDataProviderFromForeignClass {
// method data() doesn't exist in class A
@Test(dataProvider = "data", dataProviderClass = A.class)
public void test() {
}
}
class A { }
After the quick-fix is applied:
//the needed data() method is created in class A
class A {
@DataProvider
public Object[][] data() {
return new Object[][]{};
}
}
