facing an issue when the code is trying to access the System.getProperty() in Spring Test cases. working when setting the VM argument on the test case that is running, but to run each test case class, have to set the VM argument explicitly.
Is there a way to set the environment variables in the Spring before the application context loads.
Thanks in advance
Don't use System.getProperty().
Rather, use Spring's Enviornment abstraction with property sources (e.g., @PropertySource) and @Value("${propertyName}") to inject the value of the property into your production components (e.g., @Service classes, etc.).
Then, in your integration tests annotated with @RunWith(SpringRunner.class), use @TestPropertySource to override production property values with test property values.
You can do this with the help of a static block, which is executed in the first place before anything else
static { System.setProperty("", ""); } 
System.setProperty(..)in a static block in test class
