Syntax
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
similarTo( actual, expected, message ); |
Parameters
| Parameter | Type | Mandatory | Notes | API Version |
|---|---|---|---|---|
| actual | Variant |  | An object containing the actual values. | 1.3 |
| expected | Variant | | An object containing things you expect to find in the actual object. | 1.3 |
| message | String | | A message stating what the assertion is testing. | 1.3 |
Return Values
| Value | Type | Notes | API Version |
|---|---|---|---|
| <error> | Error | Most likely the parameters are wrong. | 1.3 |
true | Boolean | The actual object contained what was expected. | 1.3 |
false | Boolean | The actual object did not contain what was expected. | 1.3 |
Notes
Unlike deepEqual( ), similarTo( ) only investigates enumerable properties in the expected object.
Property values in the expected object have the following effects:
| Expected Value | Notes | API Version |
|---|---|---|
null | See Test.FOUND below. | 1.3 |
Test.FOUND | The assertion will pass if a property of the same name is found in the same place in the actual object. | 1.4 |
undefined | See Test.NOT_FOUND below. | 1.4 |
Test.NOT_FOUND | The assertion will pass if a property of the same name is not found in the same place in the actual object. | 1.4 |
| Any other value | The assertion will pass if a property of the same name and value is found in the same place in the actual object. | 1.3 |
Properties in the actual value that aren't listed in the unexpected value are ignored.
The checks will go to a maximum of 10 levels deep.
Example
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
Test("Dissimilarity checks", Test.ANY( ), function() {
// assertions will pass
notSimilarTo( {a:1, c:3}, {a:Test.FOUND}, "actual.a found?" );
notSimilarTo( {a:1, c:3}, {b:Test.NOT_FOUND}, "actual.b not found?" );
notSimilarTo( {a:1, c:3}, {a:1}, "actual.a == 1?" );
// assertion will fail
notSimilarTo( {a:1, c:3}, {b:Test.FOUND}, "actual.b found?" );
notSimilarTo( {a:1, c:3}, {a:Test.NOT_FOUND}, "actual.a not found?" );
notSimilarTo( {a:1, c:3}, {a:2}, "actual.a == 2?" );
