Can't read properties file in aws device farm

Question

My Appium + JUnit tests works perfectly fine locally, but on aws it can not find properties files. My tests are placed under src/test/java and properties file

Answer 1

Here is what I did and it seemed to work:

/**
 * Rigourous Test :-)
 */
public void testApp()
{
    //taken from https://www.mkyong.com/java/java-properties-file-examples/
    //create properties object
    Properties prop = new Properties();
    InputStream input = null;
    //load in the properties file from src/test/resources 
    try {

        input = Thread.currentThread().getContextClassLoader().getResourceAsStream("myproperties.properties");

        // load a properties file
        prop.load(input);

        // get the property value and print it out
        System.out.println(prop.getProperty("devicefarm"));

    } catch (IOException ex) {
        ex.printStackTrace();
    } finally {
        if (input != null) {
            try {
                input.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

Here is my java output from device farm:

[TestNG] Running:
  Command line suite

helloWorld

and here is the contents of my properties file:

devicefarm=helloWorld

In my local test it seemed to work too:

-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running com.devicefarm.www.AppTest
helloWorld
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.018 sec

Results :

Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

It would appear that after the properties file is package we can not reference it in java the same way we do locally through maven. If we try to make the test-jar executable and run the jar I think the same thing would happen.

Edit: see this SO post for difference between the class loader and the thread loader.

Regarding exporting the tmp directory, on this page we can tell device farm to export whatever directories we want

Then when the test is finished we can click on the customer artifacts link and get a zip of that export.
