DSL Root Element tests{}

Element tests{}

Specification

Sub Elements	Occurrences
resource	One or many
model{}	Exactly 1, required
test	One or many

Notes

• Other general elements such as outputstrategy are not recommended for unit testing. They introduce dependencies to external resources, such as files and folders. Components should be tested with no external resource dependencies.

Example

tests(name:"Example 9 Testing") {
    // the component to test.
    model (classname:"ex09.Component") 

    // Run this test once, the pre closure sets the @In before execution, 
    // The 'post' closure test the @Out after execution.
    test(name:"1: single call", 
          pre: { c ->             // this is a closure, 'c' is the component  
             c.tempC = 30         // fields can be accessed
          },         
          post:{ c -> 
             assert c.tempF == 86.0    // using groovy's asserts
    //       println c.tempF         // more statements can follow here.
          }
    )

    // Run this test against each input value from 'data'
    test(name:"2: multiple data input", 
          data:['tempC', 1, 2, 3, 5, 6, 7 ],   // data set with inputs
          post:{ c -> 
             print c.tempF
          }
    )

    // Random number generator within the script.
    Random r = new Random()

    // Run this test 100 times, let a single test fail if it runs 
    // longer than 200ms. Create random 'tempC' values from 10 ... 15 degC 
    // as input; test if the output falls in a expected range.
    test(name: "3: randomized input", count: 100, timeout:200,
          pre:{ c ->
             c.tempC = 10 + (5 * r.nextDouble())
          },

          post:{ c->
             assert c.tempF > 50 && c.tempF < 59
          }
    )
}
