BDD

A test suite begins with a call to our TestBox describe() function with at least two arguments: a title and a body closure within the life-cycle method called run(). The title is the name of the suite to register and the body function is the block of code that implements the suite. There are more arguments which you can see below:
Argument
Required
Default
Type
Description
title
true
---
string
The title of the suite to register
body
true
---
closure/udf
The closure that represents the test suite
labels
true
---
string/array
The list or array of labels this suite group belongs to
asyncAll
false
false
Boolean
If you want to parallelize the execution of the defined specs in this suite group.
skip
false
false
Boolean
A flag or a closure that tells TestBox to skip this suite group from testing if true. If this is a closure it must return boolean.
function run( testResults, testBox ){
​
     describe("A suite", function(){
          it("contains spec with an awesome expectation", function(){
               expect( true ).toBeTrue();
          });
     });
​
}
In BDD, suites can be nested within each other which provides a great capability of building trees of tests. Not only does it arrange them in tree format but also TestBox will execute the life-cycle methods in order of nested suites as it traverses the tree.
describe("A spec", function() {
​
     beforeEach(function() {
          coldbox = 22;
          application.wirebox = new coldbox.system.ioc.Injector();
     });
​
     afterEach(function() {
          coldbox = 0;
          structDelete( application, "wirebox" );
     });
​
     it("is just a function, so it can contain any code", function() {
          expect( coldbox ).toBe( 22 );
     });
​
     it("can have more than one expectation and talk to scopes", function() {
          expect( coldbox ).toBe( 22 );
          expect( application.wirebox.getInstance( 'MyService' ) ).toBeComponent();
     });
​
     describe("nested inside a second describe", function() {
​
          beforeEach(function() {
               awesome = 22;
          });
​
          afterEach(function() {
               awesome = 22 + 8;
          });
​
          it("can reference both scopes as needed ", function() {
            expect( coldbox ).toBe( awesome );
          });
     });
​
     it("can be declared after nested suites and have access to nested variables", function() {
          expect( awesome ).toBe( 30 );
     });
​
});
BDD Specs
Specs are defined by calling the TestBox it() global function, which takes in a title and a function. The title is the title of this spec or test you will write and the function is a block of code that represents the test/spec. A spec will contain most likely one or more expectations that will test the state of the SUT (software under test) or sometimes referred to as code under test.
Argument
Required
Default
Type
Description
title
true
---
string
The title of the spec
body
true
---
closure/udf
The closure that represents the spec
labels
false
---
string/array
The list or array of labels this suite group belongs to
skip
false
false
Boolean
A flag or a closure that tells TestBox to skip this suite group from testing if true. If this is a closure it must return boolean.
data
false
{}
struct
A struct of data you can bind the spec with so you can use within the body closure
An expectation is a nice assertion DSL that TestBox exposes so you can pretty much read what should happen in the testing scenario. A spec will pass if all expectations pass. A spec with one or more expectations that fail will fail the entire spec.
function run( testResults, testBox ){
​
     describe("A suite", function(){
          it("contains spec with an awesome expectation", function(){
               expect( true ).toBeTrue();
          });
​
          it("contains a spec with more than 1 expectation", function(){
               expect( [1,2,3] ).toBeArray();
               expect( [1,2,3] ).toHaveLength( 3 );
          });
     });
​
}
