II. Report improvements

The native QTP report includes several new improvements:

Tracability: Selecting a report-node will automatically focus on the relevant code-line in the script. This may sound like a cool feature at first, but a closer look revels that it only works for actions (not functions); and that in any case, using a custom report function (as most of us do) completely nullifies the feature (since you’re always at the same code line when performing the report).

Exporting: The report now has a two-click export feature, which comes with a built-in ability to export to Word and PDF documents, as well as the ability to export through a custom XSL of your choosing. You can choose between Short and Long formats (corresponding to PShort.XSL and PDetails.XSL) to get a document relevant to your needs. This blessed feature has one major flaw – It has no API support. This means that you cannot export the results automatically at the end of a test run, which is quite a miss, to say the least.

Resource Monitor: QTP can now hook onto the Windows Performance Monitor and present it as part of the test results. You can select several counters to monitor (e.g. GDI objects, memory usage etc.), and the monitor output graph will be available in special tab in the result window. You can set up a “checkpoint” for a counter (e.g. Fail the test if there are more than 500 GDI objects), facilitating a kind of a poor-man’s version of load-testing.

The fact that clicking the graph focuses on the relevant test step (as well as the other way around), provides an effective way to quickly locate problematic actions and resource usage spikes. This feature is well executed, and HP has even went the extra mile and added several unified counters that simplify monitoring the application. However, the fact that you can only monitor one process per test may leave the more advanced users with their own implementation of a resource monitor. 

Native image integration: This is a small, yet long-awaited feature. The ReportEvent command now has a new optional parameter – you can specify a path to a picture file, and it will be attached to the report node of the current event. When used in conjunction with the CaptureBitmap method, this presents a technical, yet revolutionary upgrade to the native QTP report. Finally, users can attach screenshots to their custom report events without any special functions or frameworks.

III. IDE improvements

Intellisense: IDE improvements, and the new intellisense engine in particular, is what got me excited about QTP Atlantis. 

Can create an Excel COM object provided a full intellisense for all its methods and properties, for as many levels as we’d like. Every variable set to this object also presented the same intellisense, and the autocomplete caught every variable we’ve defined or used (yes, there’s autocomplete for variable names!). The autocomplete and intellisense features worked smoothly, and presented no apparent performance issue. It’s still left to be seen how it functions in a real script, with hundreds / thousands code lines.

Tasks and Comment Pane: QTP has a new bottom pane which includes a run-of-the-mill implementation of tasks and comments. Double clicking a comment will take you to the relevant code-line, though strangely enough, you cannot do this with a task (i.e., tasks cannot be linked to specific code lines). It was mentioned that enabling the comments feature for function libraries may sometimes cause performance issues.

Dynamic code-zones: When standing inside a code block like If, While, Do, etc, the IDE will mark the relevant block with blue lines, making it much more easy to make your way inside nested blocks of this sort (somewhat like highlighting left-right bracket pairs). While it will surely make our life easier, a more robust mechanism like collapsible code-regions is still needed.

Custom Toolbars: You can add your own buttons and commands to QTP toolbars and menus. While this does not include inner-QTP macros, you can assign a program / File shortcut to your own button / menu item. It’s nice, but i think it will only gain power once QTP’s inner mechanisms will be bindable to such buttons.

IV. Miscellaneous features

General look and feel: QTP has departed from the old Tab layout, and into the more modern settings-tree layout (similar to Office, EMule, Adobe, and pretty much every other program). It’s nice, but nothing as groundbreaking as the transformation in QTP 9.0.

Bitmap Checkpoint improvements: These include presenting the size of the selected area when choosing to check only a part of an Image, as well as the ability to plug your own custom DLL for comparing images. Another great addition is the ability to see the difference between the expected and actual bitmaps in a separate tab.

API changes: QTP Automation API will receive several upgrades, the most noteworthy of which is the ability to read and write that code of the test you’ve opened. Writing the code will not effect an ongoing run-session (there goes my ambitious try-catch implementation for QTP), but it still opens the door for some creative tweaks and hacks…

Saving a test with all linked resources: For those who’re working with QC, this is a real blessing. Up until QTP 10, copying a QC saved test to your local system was a hellish procedure of changing each and every resource and action reference to your local file-system. QTP and QC Atlantis offer a one-click solution for copying a test and all its resources to your local file-system, and automatically changing all the references accordingly.

Dynamic Action Call: I’ve saved the best for last. QTP 10 presents a new native command – LoadAndRunAction. It allows you to load external actions during the run-session, without having to associate them with your test beforehand. All the run-time debug abilities will be available for these dynamically added actions, so you’re not giving anything up by using this feature. I think it’s a long awaited feature, and a well executed one.

QTP 10 revolves around 3 pivotal features, alongside several minor features (which turned out to be quite revolutionary):

I. QC integration – which (mostly) boils down to Resource Management and Source Control:

Resource Management: Although you could keep saving your resources as attachments (for backward compatibility), you can upgrade to a new, fuller mode of work. This includes a whole new Resource module in QC, and allows for some very neat tricks on Function Libraries, Tests, Object Repositories etc.

It should be noted, though, that other types of files (external excel / XML files, for example), remain as unmanaged attachments.

1. Resources have full meta-data, and have a special view pane – you can view Object-Repositories, data-tables, and function libraries code right from QC.

2. Resources are aware of their dependencies – Who relies on them, and who do they rely on. This enables a very strong warning system – when changing / deleting a resource, you’ll be alerted to the repercussions – namely, which tests, if any, might break. Also, the ability to immediately know who uses a share object repository is very useful, nearly revolutionary.

3. A very neat trick is a live, automatically updated path system – When moving a function library between folders, QC will automatically update all the tests which depend on it, so they will use it at its new location. This makes the once critical problem of hard-path-link a non-issue. Very impressive.

4. A word about the user interface – when opening a QC resource / test from QTP, the file dialog shows the items with large, crisp icons, very similar to Word’s save dialog. Everything is very clear and intuitive, as is the ability to revert back to saving / opening a test from the File-System.

5. And what about your existing projects? Well, when upgrading to QC 10, a wizard will automatically transform all you unmanaged attachments to managed resources (if you’d like it to).

Source Control: This includes a very rich line of features which are very well executed, and effectively allow you to manage a QTP project as any other code project:

1. First, the basics – QTP and QC 10 introduce a new Check-in/Check-out ability. It works similar to what you’d expect – a checked out item will be locked to all other users, and you can immediately know an item’s status by looking at its icon (green/red locks).

2. An interesting twist regards manner in which a test / resource is locked – it’s at the user level (not the local machine level). This means that if you log into QC from a different machine, you’ll have access to all your checked-out items, even if they were originally checked-out on a different local machine. The ability is implemented very well, both from QTP’s end, as well as from QC’s end.

A major enabler for source control is the new versioning feature of QC. It manifests both with a kind of instant versioning for a single resource, and with a project-wide “base-line version”, which allows you to revert your entire test framework to a previous version. Both types of versioning are supported by a surprisingly robust comparison mechanism. You can select two versions of a resource / test, a see a very detailed comparison of their respective changes. For function libraries this amounts to a “simple” text comparison, but this feature truly shines in full test comparisons.

It will present changes in the different actions and their resources (data-table, object repositories, inner code), as well as in the global test-settings, associated function libraries, recovery scenarios, and pretty much anything you could think of. The ability to drill-down into the data is very impressive; and the effective, concise manner in which the data is presented in the top level view is downright unbelievable. A nice touch is a small screen capture of the change, in case you don’t remember what “Run all rows –>Changed into-> Run a single iteration only” means (for example).

Now to the versioning mechanism itself: Whenever you check and item in, a new “version” will be created, and you’ll be able to revert back to it with ease. The snapshots are visible both from QC and QTP, and you can very easily choose which one to open. This allows you a kind of an instant undo to a single file which worked in the past, but is broken in the present.

The second mechanism presents the ability to select several folders, and create a full blown “base-line version” of them and everything they relate to. Defects, inner-connections, tests, history data, resources – all these and more will be “frozen” and preserved as a base-line. You can then choose to revert back to an old baseline, and truly regain all the abilities that were present at that time. As all the resources, attachments tests and reports will be restored, you don’t have to worry about forgetting anything, or leaving some minor resource at the wrong version. This is versioning with a vengeance – it allows you to track the AUT’s versions with your own automation versions, enabling, among other things, running automation efforts on several AUT versions at once.

For conclusion – The new abilities inherit in the connection of QTP and QC Atlantis are (or at least seem to be) revolutionary. At last, QTP projects can be natively managed as code projects; and some of the supporting infrastructure is surprisingly robust and useful.
