The purpose of the test tool is to check the behavior of high availability (HA) environments with SAP Web AS ABAP under load. The impact of HA-relevant events on the system is tested and documented. This includes the availability of system components, the impact of throughput and response time, and a check of the semantical correctness of the test results.
On this page and in the attached documents, the tool is referred to as High Availability Test Tool or, in short, as HA Test Tool.
Usage of the HA Test Tool
The tool can be used according to the end user license agreement (EULA) that you have to accept when downloading the software. The tool is no standard SAP commercial software and is provided free of charge for your convenience only.
Note that the tool is not for productive use.
Version 2.14 is available now. It is fully compatible with the version 2.13. Only the client side of the tool has changed, the server side remains on version 2.13.
In version 2.14 no major new functionality was introduced. It contains improvements for the usage of the HTTP protocol. Additionally, the display of the graphical summary with different browsers was enhanced.
Version 2.13 introduces variable event call parameters. Especially, if similar tests on several systems are done, this will help to reduce the number event property files.
In version 2.12 an HTML-based graphical summary of the test run is generated additionally.
ℹ To view the graphical summary, you need to download version 3.5.x of the open source library d3.min.js. The library is provided by d3js.org. You can use one of following links to download the library:
Don’t use version 4 of d3.min.js. It contains incompatible changes.

1.1 Reporting feedback, problems or questions
As said above, the tool is no standard SAP commercial software. Feedback, problems or questions can be reported in the “Comments” section of this page.
1.2 Getting bug fixes, updates, and new versions
SAP is not obliged to offer bug fixes, updates, and new versions. SAP will provide them at its sole discretion.
2.1 Quick start
If you are new to the HA Test Tool, chapter 1.2 (Quick Start) of the documentation describes how you make the first steps with the tool.
2.2 HA partners
Solutions of companies partnering with SAP are typically used to assure high availability of SAP systems. These companies often know the HA Test Tool. It is for example used in the test suite of SAP’s HA certification. Therefore, you can ask your HA partner for assistance in using the HA Test Tool in your HA environment.
3.1 Message ‘There is already a test running for that class’
The HA Test Tool does not allow that several tests using the same test class run in parallel. However, it is possible that the message occurs although no test is currently running for this test class. This can occur if a previous test run ended irregularly and it was not possible to mark the test as ‘finished’ on the server side. The test class can be unlocked by starting a test run with the property ‘specialaction=CleanAdminData’. For details, see the provided property template files or chapter 188.8.131.52 of the documentation.
3.2 Naming of test runs
A unique name must be assigned to each test run. This name is used to create the output directory for the test run. The start timestamp of the test is used as default (YYYYMMDDHHMMSS), but the name can be explicitly set with the property ‘testrunid’.
3.3 Varying test runs
Sometimes a series of test runs has to be conducted by varying just a few test properties. To avoid ending up with many different property files, the varying properties can be specified directly on the command line in addition to the property file that contains the properties with constant values.
3.4 Increasing the load on the server
Basically, you can increase the number of simulated users, the call frequency per user or, depending on the test class, the load put on the server by a single call. Details are described in chapter 9.3 (Scalability Guidelines) of the documentation.
