<h2 class="first" id="array-assertions">Array Assertions</h2>
<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>
