Maven Profiles - How do i get the values assigned to properties in the .properties file and assign them to variables in my class?

Question

really need some help here because I cannot seem to figure this out.

I have followed Maven Profiles – Example 2 in the following guide https://mkyong.com/maven/maven-profiles-example/

Here is my pom.xml file:

<?xml version="1.0" encoding="UTF-8"?>

Here are my properties files. I am only using two env configs at the moment 'test' and 'integration'

Here is my BaseTest class. Previously I was getting the URL values directly from the pom.xml file and assigning them to variables for use in my tests. How do I now access the values stored in the config files so I can assign them to variables for use in my tests?

When I debug, all I get are nulls. Running 'mvn package -P integration' in the terminal does not work either

However, it does say that the profile I specified is active when I execute 'mvn package -P integration'

In summary, what I am trying to achieve is to access the values stored in the config files so I can assign them to variables for use in my tests. Maybe I have misunderstood it. I am pretty new to Maven and Java and any help would be greatly appreciated

Thanks

System.getProperty is not used to retrieve values from the user-defined file. You need to load properties manually, something like the following:

public class BaseTest {

    String BaseUrl;

    public BaseTest() {
        Properties prop = new Properties();
        try (InputStream resourceAsStream = getClass().getClassLoader().getResourceAsStream("config.properties")) {
            prop.load(resourceAsStream);
            BaseUrl = (String) prop.get("url.baseUrl");
            
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

Please refer How to read data from java properties file using Spring Boot

The code you have written will only read values from environment variables.

I am not using Spring Boot. I am using JUnit. This is an API test solution. – JLee101 Aug 12 '20 at 14:45
