This topic provides information about how to use SOAtest as part of the Parasoft Application Coverage workflow. For complete information about using the Application Coverage solution, refer to the Collecting Coverage for Web Applications guide. In this section:

Introduction

The Parasoft Application Coverage solution enables you to measure application code coverage while executing tests against your running applications. You can collect coverage from a single running application or from an application that is made up of multiple backend services (you can collect coverage from all of them during execution of the same test cases). This enables you to gauge the effectiveness of your existing test suite, determine where additional tests need to be added, and more efficiently execute tests as the application evolves. You can collect application coverage by utilizing the coverage agent shipped with SOAtest for Java or dotNET, which allows you to monitor the application as tests are being performed.

Application coverage is obtained by collecting and uploading static and dynamic coverage data to DTP for viewing.

The following steps describe the Application Coverage workflow with SOAtest:

  1. Generating the static coverage file. When you have access to the application source code, the static coverage file should be generated by Jtest or dotTEST in .xml or .data format as this method comes with several advantages over the alternative. You can also generate the static coverage file by analyzing the application binaries using the coverage tool shipped with SOAtest when you do not have access to the application source code. See Generating the Static Coverage File below for more information.
  2. Attaching the coverage agent to the application under test (AUT). The coverage agent ships with SOAtest and allows you to monitor the code being executed when the AUT is running.
  3. Configuring SOAtest to connect to the coverage agent and collect runtime coverage and upload the data to DTP.
  4. Executing tests with SOAtest as part of an automated process.
  5. Reviewing the application coverage on DTP in the Coverage Explorer.

Coverage reports produced by SOAtest 2023.1 that are uploaded to DTP need to be sent to DTP 2023.1. Earlier versions of DTP will not properly process coverage reports produced by SOAtest 2023.1.

Generating the Static Coverage File

If you have access to the application source code, you should generate the static coverage file using Jtest or dotTEST in .xml or .data format if at all possible. The method has several advantages, including containing metadata about user classes, methods, and lines, as well as supporting showing source code annotated with coverage data when viewing coverage results in DTP. See Jtest or dotTEST user guide at docs.parasoft.com for more information on generating static coverage files with those tools.

You can also generate the static coverage file using the coverage tool shipped with SOAtest, though it lacks the advantages of using the source code described above. To do so, you need to run the tool independently of SOAtest, passing the binary, filter, license, and other properties when you do (see the sample license properties file below). An example using the Jtest coverage tool (jtestcov) against Parabank is shown below:

java -jar jtestcov.jar -soatest -app c:/<PATH_TO_APPLICATION>/parabank.war -include com/parasoft/parabank/parasoft/** -settings c:/<PATH_TO_LICENSE_FILE>/license.properties

The -soatest flag is used by the coverage tools to pass your SOAtest license, which is needed when you run the coverage tool independently of SOAtest as in the example above. When you run soatestcli with application coverage settings, the license is automatically passed when the coverage tool is launched. You can see all available commands and options by running: java -jar jtestcov.jar help

Configuring the Application Under Test for Coverage

Before you start collecting coverage with SOAtest, you need to configure the application under test (AUT) using Parasoft dotTEST or Parasoft Jtest. The process is outlined below; for more detailed instructions, see the Jtest or dotTEST user guide at docs.parasoft.com. Ensure that your SOAtest, dotTest, and JTest versions are in sync to avoid unexpected issues.

  1. (Optional) Customize the coverage agent by configuring the coverage agent options. This step is required if you are collecting coverage information for multiple users that are simultaneously interacting with the AUT. 
  2. Attach the coverage agent to the AUT.

Configuring the Coverage Agent

Application servers usually contain more than one application. Additionally, common server classes or application libraries do not need to be instrumented. The agent only needs to collect coverage for application source code. Instrumenting all classes would be too time consuming. For this reason, properly setting the scope of the coverage agent is very important. There are coverage agents for Jtest and dotTEST.

Jtest Coverage Agent

You can configure the Jtest coverage agent by modifying the properties in the agent.properties and passing the properties to the -javaagent argument. The agent supports several parameters (see Coverage Agent Parameters), but configuring the default settings is suitable for most cases:

jtest.agent.serverEnabled=true
jtest.agent.includes=com/myapp/data,com/myapp/common/**
jtest.agent.excludes=com/myapp/transport/*,com/myapp/autogen/**

Coverage Agent Parameters

The following table describes all properties that can be set for the agent:

jtest.agent.runtimeDataSpecifies a location on the application server for the agent to store the coverage data it collects at runtime. 
jtest.agent.includes

A comma-separated list of patterns that specify classes to be instrumented. The following wildcards are supported:

* matches zero or more characters
** matches multiple directory levels

In the following example, all classes from the com.myapp.data package and all classes from package and subpackages that start with com.myapp.common will be instrumented:

com/myapp/data/*,com/myapp/common/**

jtest.agent.excludes

A comma-separated list of patterns that specify classes to be excluded from instrumentation. The following wildcards are supported:

* matches zero or more characters
** matches multiple directory levels

In the following example, all classes from the com.myapp.transport package and all classes from package and subpackages that start with com.myapp.autogen will be excluded from instrumentation:

com/myapp/transport/*,com/myapp/autogen/**

jtest.agent.autostartEnables/disables automatic runtime data collection; the default is true.
jtest.agent.port Sets up agent communication port; the default is 8050.
jtest.agent.debug Enables/disables verbose output to console; the default is false.
jtest.agent.enableMultiuserCoverage 

Enables/disables collecting web application coverage for multiple users; the default is false. 

jtest.agent.serverEnabledActivates the agent.
jtest.agent.enableJacoco Enables the agent to collect coverage using the JaCoCo engine; the default is false.

When the properties are configured, add a -javaagent argument when starting your application server to attach the agent and include the agent configuration file:  

-javaagent:'/path/to/agent.jar'=settings='/path/to/agent.properties',runtimeData='/path/to/runtime_coverage' 

In the following example, the agent is attached to a Tomcat server with a JAVA_OPTS variable at the beginning of the catalina.sh (Linux) or catalina.bat (Windows) scripts:

if [ "$1" = "start" -o "$1" = "run" ]; then
JAVA_OPTS='-javaagent:"/home/TIA/test_impact_analysis/integration/coverage/agent.jar"=settings="/home/TIA/test_impact_analysis/integration/coverage/agent.properties",runtimeData="/home/TIA/coverage_storage"'
fi
if "%1"=="stop" goto skip_instrumentation
set JAVA_OPTS=-javaagent:"C:\TIA\test_impact_analysis\integration\coverage\agent.jar"=settings="C:\TIA\test_impact_analysis\integration\coverage\agent.properties",runtimeData="C:\TIA\coverage_storage"
:skip_instrumentation

Start the application and verify that the agent is ready by opening <host>:8050/status in your browser. You should see a JSON object that contains test, runtime_coverage, and testCase properties, for example:

{"test":null,"session":"runtime_coverage_20191008_1537_0","testCase":null}

You can also check the directory you specified with the runtimeData property (/home/TIA/coverage_storage in the example above). The directory should contain a set of static coverage data files. The files are generated when the agent is started.

dotTEST Coverage Agent

The dotTEST coverage agent can collect coverage for web applications and standalone applications. Each requires a different configuration.

Web Applications

The application under test (AUT) must be running on a machine using IIS version 7.5 or higher.

To attach the coverage agent to the AUT:

  1. Copy the <INSTALL_DIR>/coverage/dotNET/dottest_agent folder to the machine where IIS is installed and the web application is deployed.
  2. Run a console as an Administrator on this machine.
  3. Invoke the Agent Client tool on this machine to enable runtime coverage collection inside IIS:

    agent_client.exe

    agent_client initializes the environment for the web server (IIS) and behaves like a service, enabling you to execute tests and collect coverage. The service is ready and waiting for commands as long as the following message is printed to the output:

    Write 'exit' and hit Enter to close agent_client

    A test session and test can be started even if the tested website or application has not been loaded yet.

  4. Ensure that port 8050 (default port for the coverage agent) allows HTTP traffic in firewall settings on this machine. You can change the coverage agent port number if the default port is unavailable.
  5. Start the application and verify that the agent is ready by opening <host>:8050/status in your browser. You should receive the following response:

    {"session":null,"test":null}
  6. Configure soatest.properties to collect coverage for the AUT. Several application coverage parameters are supported (see Application Coverage Settings), but configuring the following settings is suitable for most cases:

    application.coverage.enabled=true
    application.coverage.agent.url=http://localhost:8050
    application.coverage.binaries=c:/<PATH_TO_APPLICATION_PDB_FILES>/bin
    application.coverage.binaries.include=<INCLUDE_PATTERN>
    application.coverage.binaries.exclude=<EXCLUDE_PATTERN>

    Be sure the path for the application binaries is to the folder containing the application PDB files.

Standalone Applications

Most users will collect coverage for web applications, but you can also collect coverage information from standalone applications.

  1. Copy the <INSTALL_DIR>/coverage/dotNET/dottest_agent folder to the machine where you intend to run the standalone application.
  2. Run the coverage_wizard.exe in that folder, specifying the following:
  3. Select the .NET CLR version used by the application.
  4. Enter the directory where the scripts generated by the wizard will be saved in the Target scripts directory field.
  5. Enable the Use Coverage Agent option and enable or disable the Collect coverage without admin privileges option as appropriate.
  6. Click Finish. The wizard will generate scripts in target script directory specified above.
  7. Run a console as an Administrator on this machine and change directories to where the scripts were generated.
  8. Execute runCamAgent.bat.
  9. Run another console as an Administrator and execute monitorCoverage.bat.
  10. Configure soatest.properties to collect coverage for the AUT. Several application coverage parameters are supported (see Application Coverage Settings), but configuring the following settings is suitable for most cases:

    application.coverage.enabled=true
    application.coverage.agent.url=http://localhost:8050
    application.coverage.binaries=c:/<PATH_TO_APPLICATION_PDB_FILES>/bin
    application.coverage.binaries.include=<INCLUDE_PATTERN>
    application.coverage.binaries.exclude=<EXCLUDE_PATTERN>

    Be sure the path for the application binaries is to the folder containing the application PDB files.

Configuring SOAtest to Collect and Upload Coverage 

With the proper configuration, SOAtest will collect application coverage during test execution. To do so, configure a SOAtest settings file (see Configuring Settings) with the following options, as appropriate:

Executing Tests to Collect and Upload Coverage

Run your tests in command line mode using the Test Configuration and settings file you have configured (see Configuring SOAtest to Collect and Upload Coverage). This step should be part of an automated process. Coverage data will be collected as tests execute and, if publishing to DTP has been enabled, uploaded to DTP.

Reviewing Coverage in DTP

Go to DTP and open the Coverage Explorer to review the application coverage achieved by your SOAtest tests.  For details on using the Coverage Explorer, see the Parasoft DTP user guide at https://docs.parasoft.com.
