eValid -- EPI Technical Specification
The eValid Programmatic Interface (EPI)
is a COM-based DLL that implements a variety of functions
to support eValid operation via a programmatic interface
that is based on control of eValid via the eValid Script Language
with additional methods/functions for special purposes.
See the Overview of EPI Organization.
Features & Facilities Provided
Here is a summary of the facilities provided with the
eValid EPI feature:
- COM-type DLL that interfaces to popular programming environments.
- Out of the box operation with C++ on Windows.
- Direct access to most eValid script commands to save programming work
and encapsulate existing internal synchronization modes.
- Immediate access to eValid playback responses
(response times and result status) via a special
in-memory internal communication block/region.
- Direct access to the DOM of the page that is currently
in the eValid browser, to allow reading and setting of any page attribute.
- Full access to result codes, so that a driver program
can take advantage of the consequence of commanded actions.
- All eValid playback synchronization and control features remain available to the eValid instance
running under EPI control.
These are the technical details on use and operation of the EPI feature.
includes the interface
to and from the current active eValid browser.
- For C++ (CPP) operation the corresponding CPP epi.h header
file is supplied with the product.
- EPI operation support structures and files
with PERL, VB, and JAVA will be released as soon as available.
will operate with any Windows environment.
- eValid script commands implemented in the interface include
most of the commands necessary to navigate, validate, analyze and synchronize
browser actions, in these categories:
- Navigation: 7 commands.
- Timing and Stopwatch: 6 commands.
- Cache Management: 2 commands.
- Wait Time/Date Manipulation: 10 commands.
- Synchronization Support: 7 commands.
- Playback Oriented: 11 commands.
- Element Oriented: 12 commands.
- Link Check Wizard: 2 commands.
- Validation: 20 commands.
- String Matching: 2 commands.
- DOM-based Synchronization Support: 4 commands.
- Extracting DOM, Page and Screen Content: 10 commands.
- Index Motion: 7 commands.
- Absolute Position: 9 commands.
- Window Management: 3 commands.
- Keyboard & Desktop Operations: 1 command.
- Script Manipulation and Annotation: 3 commands.
- eValid features such as Automatic Synchronization and Adaptive Playback are active inside
the eValid browser even when controlled through the EPI.
- The EPI interface requires
at least a current EPI and PROF feature key.
Some commands may also require a GEN or PAGEMAP feature
key for correct operation.
Web access in revenue licenses is not required.
- The EPI interface is also activated with EVAUTO/EVAL licenses which require
- Communication from the controlling program and the eValid
instance that is launched is direct "in-memory" for very low system
In-the-browser timings are accurate to << 1%.
- Control of the contents of the DOM of the current page with
get_NumElements, get_ElementAttribute and
- Direct access to the complete standard eValid
playback-time event logfile.
- Special built-in commands/methods to extract specific values from current eValid
playback-time event logfile.
