+
+<p>This example uses the <code>Y.ArrayAssert</code> object to test methods on JavaScript's
+ built-in <code>Array</code> object. The intent of this example is to introduce <code>Y.ArrayAssert</code> and its methods
+ as an alternative to the generic methods available on <code>Y.Assert</code>.</p>
+<p>The example begins by creating an example namespace and <code>Y.Test.Case</code>:</p>
+<pre class="code prettyprint">Y.namespace("example.test");
+Y.example.test.ArrayTestCase = new Y.Test.Case({
+
+ name: "Array Tests",
+
+ //-------------------------------------------------------------------------
+ // Setup and teardown
+ //-------------------------------------------------------------------------
+
+ /*
+ * The setUp() method is used to setup data that necessary for a test to
+ * run. This method is called immediately before each test method is run,
+ * so it is run as many times as there are test methods.
+ */
+ setUp : function () {
+ this.data = new Array (0,1,2,3,4,5);
+ },
+
+ /*
+ * The tearDown() method is used to clean up the initialization that was done
+ * in the setUp() method. Ideally, it should free up all memory allocated in
+ * setUp(), anticipating any possible changes to the data. This method is called
+ * immediately after each test method is run.
+ */
+ tearDown : function () {
+ delete this.data;
+ },
+
+ ...
+});</pre>
+
+<p>This <code>TestCase</code> has a <code>setUp()</code> method that creates an array for all the tests to use, as well as
+ a <code>tearDown()</code> method that deletes the array after each test has been executed. This array is used throughout
+ the tests as a base for array manipulations.</p>
+
+<h3 id="testing-push">Testing <code>push()</code></h3>
+<p>The first test is <code>testPush()</code>, which tests the functionality of the <code>Array</code> object's <code>push()</code> method
+ (other methods hidden for simpicity):</p>
+
+<pre class="code prettyprint">Y.example.test.ArrayTestCase = new Y.Test.Case({
+
+ ...
+
+ testPush : function() {
+
+ //shortcut variables
+ var ArrayAssert = Y.ArrayAssert;
+
+ //do whatever data manipulation is necessary
+ this.data.push(6);
+
+ //array-specific assertions
+ ArrayAssert.isNotEmpty(this.data, "Array should not be empty.");
+ ArrayAssert.contains(6, this.data, "Array should contain 6.");
+ ArrayAssert.indexOf(6, this.data, 6, "The value in position 6 should be 6.");
+
+ //check that all the values are there
+ ArrayAssert.itemsAreEqual([0,1,2,3,4,5,6], this.data, "Arrays should be equal.");
+
+ },
+
+ ...
+});</pre>
+
+<p>The test begins by setting up a shortcut variables for <code>Y.ArrayAssert</code>, then pushes the value 6 onto
+ the <code>data</code> array (which was created by <code>setUp()</code>). Next, <code>Y.ArrayAssert.isNotEmpty()</code> determines if the
+ array has at least one item; this should definitely pass because the <code>push()</code> operation only adds values to the array. To determine
+ that the new value, 6, is in the array, <code>Y.ArrayAssert.contains()</code> is used. The first argument is the value to look for and the second
+ is the array to look in. To find out if the new value ended up where it should have (the last position, index 6), <code>Y.ArrayAssert.indexOf()</code>
+ is used, passing in the value to search for as the first argument, the array to search in as the second, and the index at which the value should
+ occur as the final argument. Since 6 was pushed onto the end of an array that already had 6 items, it should end up at index 6 (the length of the
+ array minus one). As a final test, <code>Y.ArrayAssert.itemsAreEqual()</code> is used to determine that all of the items in the array are in the
+ correct place. The first argument of this method is an array that has all of the values that should be in the array you're testing. This assertion
+ passes only when the values in both arrays match up (the values are equal and the positions are the same).</p>
+
+<h3 id="testing-pop">Testing <code>pop()</code></h3>
+<p>The next test is <code>testPop()</code>, which tests the functionality of the <code>Array</code> object's <code>pop()</code> method:</p>
+
+<pre class="code prettyprint">Y.example.test.ArrayTestCase = new Y.Test.Case({
+
+ ...
+
+ testPop : function() {
+
+ //shortcut variables
+ var Assert = Y.Assert;
+ var ArrayAssert = Y.ArrayAssert;
+
+ //do whatever data manipulation is necessary
+ var value = this.data.pop();
+
+ //array shouldn't be empty
+ ArrayAssert.isNotEmpty(this.data, "Array should not be empty.");
+
+ //basic equality assertion - expected value, actual value, optional error message
+ Assert.areEqual(5, this.data.length, "Array should have 5 items.");
+ Assert.areEqual(5, value, "Value should be 5.");
+
+ ArrayAssert.itemsAreSame([0,1,2,3,4], this.data, "Arrays should be equal.");
+
+ },
+
+ ...
+});</pre>
+
+<p>This test also starts out by creating some shortcut variables, for <code>Y.Assert</code> and <code>Y.ArrayAssert</code>. Next, the <code>pop()</code>
+ method is called, storing the returned item in <code>value</code>. Since <code>pop()</code> should only remove a single item, <code>Y.ArrayAssert.isNotEmpty()</code>
+ is called to ensure that only one item has been removed. After that, <code>Y.Assert.areEqual()</code> is called twice: once to check the
+ length of the array and once to confirm the value of the item that was removed from the array (which should be 5). The last assertion uses
+ <code>Y.ArrayAssert.itemsAreSame()</code>, which is similar to <code>Y.ArrayAssert.itemsAreEqual()</code> in that it compares values between two
+ arrays. The difference is that <code>Y.ArrayAssert.itemsAreSame()</code> uses strict equality (<code>===</code>) to compare values, ensuring that
+ no behind-the-scenes type conversions will occur (this makes <code>Y.ArrayAssert.itemsAreSame()</code> more useful for working with arrays of
+ objects).</p>
+
+<h3 id="testing-reverse">Testing <code>reverse()</code></h3>
+<p>The next test is <code>testReverse()</code>, which tests the functionality of the <code>Array</code> object's <code>reverse()</code> method:</p>
+
+<pre class="code prettyprint">Y.example.test.ArrayTestCase = new Y.Test.Case({
+
+ ...
+
+ testReverse : function() {
+
+ //shortcut variables
+ var ArrayAssert = Y.ArrayAssert;
+
+ //do whatever data manipulation is necessary
+ this.data = this.data.reverse();
+
+ ArrayAssert.itemsAreEqual([5,4,3,2,1,0], this.data, "Arrays should be equal.");
+
+ },
+
+ ...
+});</pre>
+
+<p>The <code>testRemove()</code> method is very simple, calling <code>reverse()</code> on the array and then testing the result. Since
+ every item in the array has changed, the changes can be tested by calling <code>Y.ArrayAssert.itemsAreEqual()</code> once (instead of
+ calling <code>Y.ArrayAssert.indexOf()</code> multiple times). The first argument is an array with all the values in the reverse order
+ of the array that was created in <code>setUp()</code>. When compared with the second argument, the newly reversed array, the values in
+ each position should be equal.</p>
+
+<h3 id="testing-shift">Testing <code>shift()</code></h3>
+<p>The next test is <code>testShift()</code>, which tests the functionality of the <code>Array</code> object's <code>shift()</code> method:</p>
+
+<pre class="code prettyprint">Y.example.test.ArrayTestCase = new Y.Test.Case({
+
+ ...
+
+ testShift : function() {
+
+ //shortcut variables
+ var Assert = Y.Assert;
+ var ArrayAssert = Y.ArrayAssert;
+
+ //do whatever data manipulation is necessary
+ var value = this.data.shift();
+
+ //array shouldn't be empty
+ ArrayAssert.isNotEmpty(this.data, "Array should not be empty.");
+
+ //basic equality assertion - expected value, actual value, optional error message
+ Assert.areEqual(5, this.data.length, "Array should have 6 items.");
+ Assert.areEqual(0, value, "Value should be 0.");
+
+ ArrayAssert.itemsAreEqual([1,2,3,4,5], this.data, "Arrays should be equal.");
+
+ },
+
+ ...
+});</pre>
+
+<p>The <code>shift()</code> method removes the first item in the array and returns it (similar to <code>pop()</code>, which removes the item
+ from the end). In the <code>testShift()</code> method, <code>shift()</code> is called and the item is stored in <code>value</code>. To ensure
+ that the rest of the array is still there, <code>Y.ArrayAssert.isNotEmpty()</code> is called. After that, <code>Array.areEqual()</code> is
+ called twice, once to test the length of the array and once to test the value that was returned from <code>shift()</code> (which should be
+ 0). As a last test, the entire array is tested using <code>Y.ArrayAssert.itemsAreEqual()</code> to ensure that all of the items have shifted
+ into the appropriate positions in the array.</p>
+
+<h3 id="testing-splice">Testing <code>splice()</code></h3>
+<p>The next test is <code>testSplice()</code>, which tests the functionality of the <code>Array</code> object's <code>splice()</code> method:</p>
+
+<pre class="code prettyprint">Y.example.test.ArrayTestCase = new Y.Test.Case({
+
+ ...
+
+ testSplice : function() {
+
+ //shortcut variables
+ var Assert = Y.Assert;
+ var ArrayAssert = Y.ArrayAssert;
+
+ //do whatever data manipulation is necessary
+ var removed = this.data.splice(1, 2, 99, 100);
+
+ //basic equality assertion - expected value, actual value, optional error message
+ Assert.areEqual(6, this.data.length, "Array should have 6 items.");
+
+ //the new items should be there
+ ArrayAssert.indexOf(99, this.data, 1, "Value at index 1 should be 99.");
+ ArrayAssert.indexOf(100, this.data, 2, "Value at index 2 should be 100.");
+
+ ArrayAssert.itemsAreEqual([0,99,100,3,4,5], this.data, "Arrays should be equal.");
+ ArrayAssert.itemsAreEqual([1,2], removed, "Removed values should be an array containing 1 and 2.");
+
+ },
+
+ ...
+});</pre>
+
+<p>The <code>splice()</code> method is one of the most powerful <code>Array</code> manipulations. It can both remove and add any number of items
+ from an array at the same time. This test begins by splicing some values into the array. When calling <code>splice()</code>, the first argument
+ is 1, indicating that values should be inserted at index 1 of the array; the second argument is 2, indicating that two values should be
+ removed from the array (the value in index 1 and the value in index 2); the third and fourth arguments are values that should be inserted
+ into the array at the position given by the first argument. Essentially, values 1 and 2 should end up being replaced by values 99 and 100 in
+ the array.</p>
+<p>The first test is to determine that the length of the array is still 6 (since the previous step removed two items and then inserted two, the
+ length should still be 6). After that, <code>Y.Assert.indexOf()</code> is called to determine that the values of 99 and 100 are in positions
+ 1 and 2, respectively. To ensure the integrity of the entire array, <code>Y.ArrayAssert.itemsAreEqual()</code> is called on the array, comparing
+ it to an array with the same values. The very last step is to test the value returned from <code>splice()</code>, which is an array containing
+ the removed values, 1 and 2. <code>Y.ArrayAssert.itemsAreEqual()</code> is appropriate for this task as well.</p>
+
+<h3 id="testing-unshift">Testing <code>unshift()</code></h3>
+<p>The next test is <code>testUnshift()</code>, which tests the functionality of the <code>Array</code> object's <code>unshift()</code> method:</p>
+
+<pre class="code prettyprint">Y.example.test.ArrayTestCase = new Y.Test.Case({
+
+ ...
+
+ testUnshift : function() {
+
+ //shortcut variables
+ var Assert = Y.Assert;
+ var ArrayAssert = Y.ArrayAssert;
+
+ //do whatever data manipulation is necessary
+ this.data.unshift(-1);
+
+ //basic equality assertion - expected value, actual value, optional error message
+ Assert.areEqual(7, this.data.length, "Array should have 7 items.");
+
+ //the new item should be there
+ ArrayAssert.indexOf(-1, this.data, 0, "First item should be -1.");
+
+ ArrayAssert.itemsAreEqual([-1,0,1,2,3,4,5], this.data, "Arrays should be equal.");
+
+ },
+
+ ...
+});</pre>
+
+<p>Working similar to <code>push()</code>, <code>unshift()</code> adds a value to the array, but the item is added to the front (index 0) instead of
+ the back. This test begins by adding the value -1 to the array. The first assertion determines if the length of the array has been incremented
+ to 7 to account for the new value. After that, <code>Y.ArrayAssert.indexOf()</code> is used to determine if the value has been placed in the
+ correct location. The final assertions tests that the entire array is expected by using <code>Y.ArrayAssert.itemsAreEqual()</code>.</p>
+
+<h3 id="running-the-tests">Running the tests</h3>
+
+<p>With all of the tests defined, the last step is to run them:</p>
+
+<pre class="code prettyprint">//create the console
+(new Y.Test.Console({
+ verbose : true,
+ newestOnTop : false,
+ filters: {
+ pass: true,
+ fail: true
+ }
+})).render('#testLogger');
+
+Y.Test.Runner.add(Y.example.test.ArrayTestCase);
+
+//run the tests
+Y.Test.Runner.run();</pre>
+
+
+<p>Before running the tests, it's necessary to create a <code>Y.Test.Console</code> object to display the results (otherwise the tests would run
+ but you wouldn't see the results). After that, the <code>Y.Test.Runner</code> is loaded with the <code>Y.Test.Case</code> object by calling
+ <code>add()</code> (any number of <code>Y.Test.Case</code> and <code>TestSuite</code> objects can be added to a <code>Y.Test.Runner</code>,
+ this example only adds one for simplicity). The very last step is to call <code>run()</code>, which begins executing the tests in its
+ queue and displays the results in the <code>Y.Test.Console</code>.</p>
