At a Glance

PREEvision supports test engineers and test managers in all phases of E/E development:

Test Engineering and Test Management in PREEvision
The integrated test engineering and test management support in PREEvision.

From the description of requirements, test specifications and test items, to the design and implementation of tests, the planning of tests, the execution and documentation as well as evaluation and analysis of test results – the tool assures quality in all phases of an E/E project.

Functions / Features

Test Engineering

PREEvision Testing - Test Engineering
Create and describe the test items with the associated requirements.

During test engineering, test scenarios covering all product requirements are developed. For this purpose, test specifications and test cases are created and managed in a structured way in PREEvision and then serve as the template for subsequent test implementation.

The requirements engineering capability of PREEvision allows all project partners to have a common understanding of the product to be developed and its quality.

For efficient testing, all test results can be directly associated with the requirements. In the test engineering phase, the primary goal is to find the most efficient test scenarios covering all the requirements. This involves creating structured test specifications and managing them with PREEvision. The specifications are composed of individual test scenarios. The test items serve as a template for the later test implementation.

Use PREEvision to:

  • Create and describe requirements and test scenarios
  • Assign requirements to test items in a simple way
  • Plan test phases
  • Export test items for use in test design tools
  • Coordinate and configure test environments and devices under test


Test Data Management

PREEvision manages file-based test data such as test scripts and test logs. Configuration, change and version management utilize the concepts and user interface of the widely used Subversion (SVN) tool.


PREEvision Testing - Test Data Management
The working copies view shows the files in a file system including their revision status.

Use PREEvision to:

  • Import and manage file-based test data
  • Version control of file-based test data
  • Control and trace changes

Automatic and Manual Test Runs

PREEvision manages and visualizes automatic tests with the corresponding test scenarios. The actual test case is initialized in a test execution tool such as CANoe. The results of the automatic test cases are imported from test reports of the execution environment.

If test automation is not beneficial, inefficient or even impossible, manual test cases are described and managed, and test scenarios are assigned in individual test steps in PREEvision. With manual tests, results are entered directly in PREEvision.

Use PREEvision to:

  • Manage and visualize automatic test sequences with associated test items
  • Import detailed test scripts from test design tools
  • Manage the imported test scripts
PREEvision Testing - Automatic Test Runs
Automated test sequences (test scripts) after import into PREEvision with the associated test items.

Use PREEvision to

  • Describe manual test sequences in consecutive test steps
  • Group test steps that belong together
  • Assign test items to test sequences
PREEvision Testing - Manual Test Runs
Manual test runs with the associated test items.

In general each test run can be evaluated again afterwards if new information becomes available (e.g. a fault is found in a test rig).

Use PREEvision to:

  • Assign an additional verdict: Evaluate a verdict negatively at a later time, and in this case enter a comment that explains the reason.
  • Reverse a verdict: Evaluate a verdict positively at a later time, and in this case enter a comment that explains the reason.
PREEvision Testing - Test Re-Evaluation
Post-evaluation of negative (1) and positive (2) evaluated test runs.

Visualization, Monitoring and Analysis

PREEvision Test Monitoring Cockpit
Visualization of decision-relevant information.

The cockpit view provides test managers with the current status of all test projects. The most important information is collected and visualized in the main window.

Charts provide a well-laid-out and quick-to-understand representation of key information, which serves as the basis for management of all test activities in a targeted way.

The cockpit view can be completely adapted to the needs of individual organizations thanks to its editor. Using trend analysis, PREEvision maps the development of key figures (metrics) over time. A variety of different diagrams are available for visualization of metrics and results.

The cockpit view informs test managers about all test projects and their status. In the main window you find a summary and visualization of the most important information. Diagrams and charts are the basis for a target-oriented management of all test activities. A simple editor allows the easy adaption of the cockpit view to the needs of managers and decision makers.

Use PREEvision to:

  • Control and measure all test activities
  • Visualize crucial status information
PREEvision Testing - Monitoring
The cockpit view visualizes crucial information to facilitate faster decisions.

The trend view shows the development of characteristic values in the course of time. For the visualization different diagrams are available.

Use PREEvision to:

  • Show the trends in test results
  • Show the trends in test activities
PREEvision Testing - Trend Analysis
The trend view offers a faster and better overview over the progress of characteristic values.
