Download Effective GUI Testing Automation: Developing an Automated by Kanglin Li PDF

By Kanglin Li

The most important difficulties i have encountered with try automation should not technical yet managerial: it really is infrequent that people with the making plans and decision-making authority have the neccessary knowing of what attempt automation is and the way it suits into the development/testing cycle. it isn't "sped-up handbook trying out" and it isn't "record and playback", even though it may perhaps comprise components of either and extra. it is a improvement attempt in its personal correct and desires to be controlled as such.

I've used a number of the significant commerical automation instruments and built others in-house and none of them are the silver bullets their proprietors (and in-house evangelists) declare they're. some time past, you'll were hard-pressed to make the case to administration for writing your personal in-house complete featured GUI checking out software. It required a developer ability set that many in QA - even these on automation groups - do not constantly have in adequate intensity (not to say the truth that, such a lot who do have the talents decide to make extra greenbacks over in development).

What the maturing of .NET and Microsoft's UI Automation Library have performed, i think, is placed the writing at the wall for advertisement UI try out instruments reminiscent of QTP and sensible Tester (WinRunner is on life-support, quickly to be removed).

As extra computing device purposes themselves gravitate in the direction of .NET and, more and more, local 64-bit, advertisement instruments are suffering to maintain velocity.

This publication demonstrates the benefits automation builders have in developing their very own automation instruments for .NET-based purposes, thank you essentially to the shut tie-in with the mirrored image namespace, UI automation libraries and COM interop serivces. The C# or VB.NET language ability set, whereas no longer trival, isn't the comparable as writing C++ COM/ATL code, which might were the single believable alternative a decade in the past to create an automation instrument.

People coming from a script language coding heritage, ideally with a few local Win32 programming of their earlier, may still transition to .NET languages quite easily. in the event that they have a superb take hold of of the diversities among unit trying out, integration and process trying out, there is a lot during this ebook to use either actually and to take advantage of as a conceptual base for growing an automation device much more adapted for your particular software needs.

I do not often touch upon different experiences yet i must say the examples within the ebook labored simply effective on my XP SP3 laptop atmosphere, operating the most recent model of the .NET framework. Having been round software program improvement and trying out for 20+ years i am certain that person's tricky adventure used to be real, yet it is unfair to provide all readers the influence the publication includes undesirable code.

What the e-book does include in abundance is painfully undesirable English. i do not say this with any disrespect in the direction of the authors. i am yes they're doing their most sensible and, as somebody who speaks just one language (and struggles frequently with it), I admire someone who makes an attempt to profit and use one other, particularly in a technical field.

My feedback is aimed toward the Sybex editors, who particularly dropped the ball the following by way of letting a tremendous ebook out the door with no sufficient review.

Sample text

When a technology is implemented in an organization, the testing tool will able to test the new features. If the tool lacks the capability to test new features, developers can upgrade the tool. 12 Chapter 1 • GUI Testing: An Overview Intuitive test automation Using a fully automated testing tool is natural. You just need to feed the tool an application under test. The tool will take care of the GUI identification, data and test script generation, test execution and save the test results. Because the tool actively looks for GUI components to test, it creates a minimum number of test scripts and tests all of the components.

They can also make multiple copies of the data store and assign different values to each test case. It is believed that once the test script executes, it will not find bugs by running against the same test cases. Multiple copies of the data store will enable the scripts to test as many branches of the application as possible, thus maximizing the possibility of finding bugs. Data-Driven Test Scripts All the available testing tools have at lease two features to brag about: one is their capture/ playback capability, the other is their capability for data-driven script generation.

The data-driven test script is also on the wish list of tool vendors because many testing tools don’t know how to generate testing data automatically. When they record scripts, they ask the users to enter testing data via a wizard. The wizard doesn’t have the power to automate the process. In other words, data is often generated after test code in the scripts using these tools, and test scripts are not data-driven. In this book, the approach will be to conduct a GUI survey of the application under test.
