Update README links
GTXiLib (spelled GTX eye lib) is library of APIs for iOS accessibility testing that can be easily embedded into any test framework or tool, for example it has XCTest integration and can be used with EarlGrey. GTXiLib works by installing “checks” on your existing test cases so that before test teardown the checks are evaluated on your app to look for accessibility issues such as missing labels.
To install GTXiLib on all the tests of a specific test class add the following snippet of code to it.
// Include the GTXiLib umbrella header.
#import <GTXiLib/GTXiLib.h>
+ (void)setUp {
[super setUp];
// ... your other setup code (if any) comes here.
// Install GTX on all tests in *this* test class.
[GTXiLib installOnTestSuite:[GTXTestSuite suiteWithAllTestsInClass:self]
checks:[GTXChecksCollection allGTXChecks]
elementBlacklists:@[]];
}
Once installed, GTX will run all registered accessibility checks before test case tearDown and fail the test if any accessibility checks fail. Note that code is being added to +setUp method not the instance method -setUp since GTX must only be installed once (for a given test run).
GTXiLib APIs support a practical solution for improving accessibility of large projects which may not have included accessibility from the get go - incremental accessibility. Adding GTXiLib to a project that is already halfway through development may leads to several test failures and fixing them at once can be time consuming and tedious. To solve this problem incrementally:
GTXTestSuite's suiteWithClass:andTests: method to create a test suite with only the tests cases that have been fixed and add GTXiLib only to that suite.Once the code is checked into your repo GTXiLib will catch any new failures in those tests. From this point:
If at any point all the tests of a test class are in the suite use suiteWithAllTestsInClass: method instead of listing all the methods, this also ensures that new methods added to the class are automatically under accessibility checking.
If GTXiLib is installed on every test in your project, use suiteWithAllTestsFromAllClassesInheritedFromClass: to automatically add accessibility checking to any test case added.
GTXiLib has APIs that allow for creation of your own accessibility checks (in fact it does not have to be related to accessibility, for example i18n layout checks or even memory usage checks). To create new checks use GTXiLib's checkWithName:block: API and provide a unique name and block that evaluates the check and returns YES/NO for success/failure. Add the newly created check to the array of checks being passed on to GTXiLib via the install API call.
When GTXiLib fails it has most likely found an accessibility bug and you must fix it. But due to various team priorities it may not be possible to do so right away in which case you have the following options at your disposal:
suiteWithAllTestsInClass:exceptTests:.But if you believe GTXiLib has caught a bug that is not an accessibility issue please let us know by filing a bug or better fix it for everyone.
To prioritize and improve GTXiLib, the framework collects usage data and uploads it to Google Analytics. More specifically, the framework collects the MD5 hash of the test app's Bundle ID and pass/fail status of GTXiLib checks. This information allows us to measure the volume of usage. For more detailed information about our analytics collection, please peruse the GTXAnalytics.m file which contains the implementation details. If they wish, users can choose to opt out by disabling the Analytics by adding the following code snippet in test’s +(void) setUp method:
// Disable GTXiLib analytics. [GTXAnalytics setEnabled:NO];
