In the following example, the if condition is evaluated true for both Boolean and int values. In Groovy, non-zero integers, non-null values, nonempty strings, initialized collections, and a valid matcher are evaluated as Boolean true values. This is known as Groovy Truths. Let's take a look at the following code:

  if(condition2){
    println("Condition 2 satisfied")
  }else{
    println("Condition 2 failed")
  }
}else{
  println("Condition 1 failed")
}
