Capture/Playback Systems |
Here is a brief summary of the main features of the most-commonly used capture/replay systems for UNIX platforms. This information is gathered from sources believed to be reliable, but no warranty applies here.
| Product Name Supplier | TrueTime Mode
Records exactly what the user types and how the mouse was moved and clicked. | Object Mode
Helps make a test recording survive minor changes in the underlying GUI, e.g. button placement, etc. | Additional Comments
Some suggestions about how the products compare. Estimated 1-seat Price Multiplier |
| CAPBAK/X SR/Inc. TestWorks | Based on use of Xtrap/XTestExtension1 (selected automatically).
Reverts to TrueTime mode automatically during recording Automatic Output Synchronization (AOS) assures robust playback in pure TrueTime recording | ObjectMode is based in instrumented Xt toolkit
used in Motif applications
~98% of all UNIX window apps use Motif. | The built-in Optical Character Recognition
(OCR) Engine gives font-independent extraction
("screen scraping") of ASCII information.
CAPBAK's goal/bias is to produced a recording in any circumstance that has a high likelihood of playing back successfully. A recording successfully made is expressed in C and can be edited easily if needed. Price Multiplier 1.0 |
| Xrunner Mercury | TrueTime mode exists but as a option.
Uses Xtrap. No AOS capability | Object mode through instrumentation of Xt toolkit.
MI has partial support for several other older toolkits e.g. XVT and iLog Views that are not fully Motif/Xt compliant. | MI emphasizes human programming of the playback files (called "scripting").
Recordings may or may not play back on the first try and may require editing to be reliable. Price Multiplier ~ 2.2 |
| QAPartner Segue | TrueTime Mode exists only as a default (some doubt there is any truetime mode at all). | Object Mode available via instrumented Xt toolkit. | Emphasis appears to be on "scripting".
Recordings may or may not play back on the first try and may require editing to be reliable. Price Multiplier ~ 1.5 |
| preVueX Rational (Originally | Based on use of recordings from the X protocol communication between Xdisplay and application. | Object mode is not possible with this technology. | This product is excellent for generating load
information because one can replay a recorded
session multiple times to simulate multiple users.
