Abstract

Architecture that provides a convenient and effective test tool for testing and ensuring that webpages using micro-browsers are sufficiently designed and operational. A task library is developed for manipulating browsers on a handheld device, and includes one or more seamless methods that operate the different browsers in the same way. Seamless virtual functions that manipulate different micro-browsers include, but are not limited to browser launch, exiting a browser, navigating to a home page, clearing a cache, navigating to a webpage, reloading a webpage, getting the current info for a webpage, navigating back to a webpage, checking a page title, and capturing a screen, for example. Device features can also be manipulated to ensure consistency across the testing process.

Claims

1. A computer-implemented method of testing a webpage, comprising acts of:

developing a library of tasks that control different micro-browsers when running on different handheld devices, the library including micro-browser properties, device properties defined in the tasks, and at least one method that operates the different browsers in a same way, wherein a task defines operations on the micro-browser under test;

creating tasks for the library that control the handheld devices;

executing tasks to test display of a webpage in the different micro-browsers when operating on the handheld devices;

capturing a screenshot image of the display of the webpage, to obtain an image of a test feature;

comparing the image of the test feature to an expected display webpage image;

processing results of the comparing to determine quality of design of the webpage; and

utilizing a microprocessor that executes instructions stored in a memory associated with at least one of the acts of developing, creating, executing, capturing, comparing, or processing.

2. The method of claim 1, further comprising:

capturing a screenshot image by creating a screen dump image of a webpage test result based on a task;

trimming the screenshot image of the screen dump image to obtain the image of the test feature; and

comparing the trimmed screen dump image of the webpage test result to an expected display webpage image to determine the quality of the webpage design.

3. The method of claim 1, further comprising defining coordinates that preserve webpage content during the test.

4. The method of claim 1, further comprising writing a test script that exercises manipulation of a micro-browser on a device when presenting a webpage.

5. The method of claim 1, wherein the tasks executed include launching a browser, navigating to a home webpage, navigating to a different page, navigating back to a previous webpage, reloading a webpage, checking a webpage title, getting current webpage information, capturing a screen of a webpage, clearing a cache, and exiting the browser.

6. A computer-implemented test system, comprising:

a library of tasks configured to enable control of different micro-browsers when running on different handheld web-accessible devices, the library including micro-browser properties, device properties defined in the tasks, and at least one method that operates the different micro-browsers in a same way, wherein a task defines operations on the micro-browser under test;

a test framework configured to execute the tasks to test a display of a webpage in the different micro-browsers when operating on the handheld web-accessible devices;

a logging component configured to capture screen dump information to produce a screenshot image of the display of the webpage, representing a test feature image;

a compare component configured to compare the test feature image to an expected display webpage image; and

a microprocessor configured to execute computer-executable instructions in a memory associated at least with the test framework.

7. The system of claim 6, wherein the compare component compares display expected results of the webpage to display test results to verify design of the webpage.

8. The system of claim 7, wherein the compare component trims the screenshot image of the display of the webpage prior to comparison to obtain the test feature image.

9. The system of claim 6, wherein the logging component logs test information and captures the screen dump information.

10. The system of claim 6, further comprising a script component configured to enable writing a test script that accesses one or more tasks of the library to run a micro-browser on a particular handheld web-accessible device and test the webpage in the micro-browser of the particular handheld device.

11. The system of claim 6, wherein the library includes tasks that launch a micro-browser and exit the micro-browser.

12. The system of claim 6, wherein the library includes tasks that navigate to a home webpage, navigate to a particular webpage, and navigate back to a previous webpage.

13. The system of claim 6, wherein the library includes tasks that reload a webpage and clear a cache.

14. The system of claim 6, wherein the library includes tasks that get current information, check a webpage title, and capture a screen.

15. The system of claim 6, wherein the handheld web-accessible devices include a smart cell phone.

16. A computer-implemented test system, comprising:

a library of tasks configured to enable control of different micro-browsers when running on different handheld web-accessible devices, the library including micro-browser properties, device properties defined in the tasks, and at least one method that operates the different micro-browsers in a same way, wherein a task defines operations on the micro-browser under test;

a test framework configured to execute the tasks to test display of a webpage in the different micro-browsers when operating on the handheld web-accessible devices;

a logging component configured to log test information and capture screen dump information to produce a screenshot image of the webpage, representing a test feature image;

a compare component configured to compare an expected display results image of the webpage to the test display results feature image to verify design of the webpage; and

a microprocessor that executes computer-executable instructions in a memory associated at least with the test framework.

17. The system of claim 16, wherein the compare component trims the screenshot image of the display of the webpage prior to comparison to obtain the test feature image.

18. The system of claim 16, wherein the library includes one or more methods, micro-browser properties, and device properties defined in the tasks that launch a micro-browser, exit the micro-browser, navigate to a home webpage, navigate to a particular webpage, and navigate back to a previous webpage.

19. The system of claim 16, wherein the library includes one or more methods, micro-browser properties, and device properties defined in the tasks that reload a webpage, clear a cache, get current information, check a webpage title, and capture a screen.

20. The system of claim 16, wherein the logging component further computes and provides a pass rate of test cases and identifies failure case information.
