STRIDE Framework tests (script and native target implmentations) are controlled by a host computer, physically connected to the target via a configurable communication channel (TCP/IP or serial port). This article describes some common usage patterns and presents several examples.

Prerequisites

In order to run STRIDE tests, the following prerequisites are required.

Host

Target

  • Target transport configured
  • Target built with STRIDE library and some STRIDE source instrumentation. If any native test units have been written, these must be included in the build also.
  • Target app running [1]

Preparing to Run Your Tests

Tests are initiated on the host by running the program stride on the host computer. See the linked article for reference information.

In order for stride to run your tests, the STRIDE database (.sidb) file that was produced as part of the target build must be accessible to the program via the host filesystem. This is trivial to accomplish when the target is built on the host computer (as when building and running tests off-target) or when the host and target computers are running the same operating system and are connected via LAN. But for dissimilar operating systems, you will need to mount the target filesystem on the host computer. (Many of our customers use Samba to accomplish this.)

Running Tests

The following command line illustrates how to run some STRIDE tests without publishing results to STRIDE Test Space.

We assume the following:

  • We are testing against a target build that contains the following native code test units: myTest1, myTest2 and myTest3.
  • I also want to run host based tests implemented in a perl test module, myScriptTests.pm.
  • The target device is running, and is available on the LAN via TCP/IP at 192.168.0.53

The command line to run the desired tests would be:

stride -r "myTest1;myTest2;myTest3" -r myScriptTests.pm --database="/my/path/targetApp.sidb" --device=TCP:192.168.0.53:8000

A couple of things to note:

  • If you are running tests of a shared location and others may be running tests using the same referenced database, you should specify a unique output file location (via the -o option) to prevent overwriting the output file.
  • If you will be running many tests against a specific database and/or device, consider setting environment variables to the corresponding values, or put command line options into an options file (via the -O option).
  • You can refer to the device address using a DNS name if desired (e.g. TCP:testcomputer:8000)
  • For more information and examples, see Listing Test Units and Running A Subset of Tests.

= Running All Tests

By default, stride will not run any tests if no --run options are specified. A simple way to run all target based test units (tests implemented in native code on the device) is to specify the wildcard parameter to stride - specifically:

stride --database TestApp.sidb --device TCP:128.0.0.1:8000 --run=*

This will cause all test units that have been captured in the STRIDE database to be executed.

There is no way to run all test modules since we don't capture information about these in the STRIDE database. However, if you organize your test modules in a directory hierarchy, the runner provides a convenient syntax for executing all test modules in a directory - for example:

stride --database TestApp.sidb --device TCP:128.0.0.1:8000 --run=path\to\my_directory

will recursively search my_directory for script test modules (identified by file extension) and execute each as it is found.

Publishing Test Results

Saving Results to the Local Disk

When stride is executed to run tests, the following files are written to the current directory. By default, they are named after the specified database. You can specify a different name and location by using the -o option when you run stride. If these files already exist, they are overwritten.

[database_name].xml
Raw xml test output.
[database_name].xsl
Stylesheet to format the xml file for viewing in a web browser. (This file is automatically downloaded only if you are connected to the Internet.)

Displaying Local Results Data

If you open the xml file in a browser, the xsl stylesheet (if present) will be automatically applied to the xml so that the data is rendered in html within the browser.

Publishing Results to STRIDE Test Space

stride can also be instructed to upload test results to STRIDE Test Space.

Example: Desktop Testing with Publication to Test Space

This example demonstrates the running of specified target tests followed by publication of the results to STRIDE Test Space.

Here, we create an options file since the command line is getting very long. (We could put several of these option values in environment variables instead if desired.)

The option file is named myOptions.txt, is located in the current directory and contains the following text:

--database "/my/path/targetApp.sidb"
--device TCP:192.168.0.53:8000
-r /{myTest1;myTest2; myTest3}
-u
--testspace https://username:password@mycompany.stridetestspace.com
--project "Super Repeater"
--space "Input Processor"
-o myoutputfile.xml

The command line is then:

stride -O "myOptions.txt"

Note: In order for publishing to succeed, the username/password must be correct and the project and space must already exist. If you are using TestSpace for the first time, you should check with your administrator about how to create projects and spaces.


Notes

  1. If target is multi-process, both the target and the STRIDE I/O daemon process must be started.
