What does the below line of code mean?

String ProcessStr =(!test.isRunningTest())? Customsetting__c.getInstance('Process').value__c:'0';

    Note: this is Bad Code. If you need the value of a custom setting in a unit test, the custom setting should be created as part of the test setup. – sfdcfox Feb 20 '18 at 16:16
  • Never use Test.isRunningTest unless you can find no alternative. – Adrian Larson Feb 20 '18 at 16:37

The documentation is quite clear on what this specific method does, and the name is essentially self documenting:

  • isRunningTest()
    Returns true if the currently executing code was called by code contained in a test method, false otherwise. Use this method if you need to run different code depending on whether it was being called from a test.

As for ternary syntax (?:), you can see that documented in the Apex Developer Guide under Expression Operators:

? :

x ? y : z

Ternary operator (Right associative). This operator acts as a short-hand for if-then-else statements. If x, a Boolean, is true, y is the result. Otherwise z is the result. Note that x cannot be null.

So the translation of your code to plain English is essentially:

If this code is running in a live transaction (not a test), then get the value from a custom setting. Otherwise, use a value of '0'.
