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.

Settings or Preferences | Editor | Inspections | Java | TestNG

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[][]{};
  }
}

Availability

By default bundled with: IntelliJ IDEA 2024.1, Qodana for JVM 2024.1,
Can be installed with plugin: TestNG, 241.18072
