Constructor Undefined Error - Java

Question

Am trying call a method from another class which is present in different files.

Main File :

public class Test extends AndroidTestCase {
    mTestUtils = new TestUtils(this, TAG, OUTPUT_FILE);

Second File :

public class TestUtils {
    public TestUtils(Context context, String tag, String outputFile) {

        mContext = context;
        mTag = tag;
        mOutputFile = outputFile;
    }
}

It throws Constructor undefined error. Any help would be appreciated.

Please provide a [mcve]. Your first snippet of code wouldn't compile for *various* reasons, we don't know the types of `TAG` or `OUTPUT_FILE`, nor have you included the full error text. — Jon Skeet, Jul 28 '17 at 12:20
`Context context` - does `AndroidTestCase` extend resp. implement `Context`? — Erich Kitzmueller, Jul 28 '17 at 12:20
As a side note `Public class Test` should be `public class Test` — Xvolks, Jul 28 '17 at 12:24

you are doing

TestUtils(this, TAG, OUTPUT_FILE);

but this is not a context in that case.

the method getContext() will provide you that, just look the doc

might be helpful to explain how signatures work. But this does answer the question. – Jason V Jul 28 '17 at 12:24

the signature of TestUtils constructor takes object of type Context and when you do this in Test class

new TestUtils(this, TAG, OUTPUT_FILE);

you're not passing Context object

instead of this you should pass Context object
