Description | Workflow test runs can be configured to automate tests |
schema location | http://fews.wldelft.nl/schemas/version1.0/workflowTestRun.xsd |
Originally developed for testing purposes, the WorkflowTestRunner to run workflows automatically in a Stand Alone environment is now also used in “live” systems. This use has been proven to be performing well in practice and is now fully supported by Deltares. See also 03 Testing workflows with the WorkflowTestRunner in SA mode |
This module allows you to automate test and to run workflows with or without starting-up the user interface. As such, it can also be used to automate tasks in stand-alone systems, for example in combination with the windows task scheduler (or cron in linux systems).
The workflow test runner can also be integrated into a CI/CD pipeline. For more information, please see: Workflow Test Runner in Azure Devops

The workflow test run configuration consists of two main parts: General configuration and Activities
Give an optional description of the workflow test run
Optional directory references which can be use to refer to directories using a short name.
attributes:
Optional time to use as system time while running the workflow test. If the system time is not given it is taken from the current computer time.
attributes:
Since 2021.01. It is possible to generate a JUnit XML compliant XML report with the test results. Currently only junitXml is supported. This can typically be used in a build pipeline like Azure Devops or Teamcity.
For example:
<testReport dir="%REPORT_DIR%"> <reportType>junitXml</reportType> </testReport> |
In case one of the activities fail, a failed test will be reported.
The activities of the workflow test run configuration that will be carried out. You can use activities in any order you like, they will be executed as ordered in your configuration file.
This activity can be used to remove files or directories to e.g. create an initial situation or to clean up after running the test.
attributes:
Activity can be used to copy files or directories between two locations e.g. to copy files to import to the applications import directory
attributes:
Runs the workflow file with the given id. The id must be known in the application environment.
choice:
taskProperties: Use a taskProperties configuration block to define how to run the workflow
WftrWorkflowGroup:
Exports the given time series to PI formatted file.
Since 2021.01 the version of the PI format can be specified using the piVersion element.
attributes:
Exports the log messages produced during the last workflow run.
Changes the system time.
Compares an exported file with a given reference file. The comparison will be visible in the log output of the application environment.
attributes:
Refreshes datastore. Empty element.
Search for the presence of text in a file
attributes:
Search if text doesn't occur in a file
attributes:
Let process sleep for configured amount of milli seconds
Workflow test runs can either be started from within a FEWS stand-alone application, or within a JUnit test.
To start a workflow test in DELFT-FEWS open the debug menu (F12) and select 'run workflow test' (C). This will open an open file dialog in which you can select a workflow configuration file to run in the current environment.
Workflow test runs can be started in JUnit tests in order to build (nightly) regression tests. To do so, initialize the test environment and create a datastore to pass to the workflow constructor. Next code snipped demonstrates the use of WorkflowTestRun in JUnit:
.... // init test application App.init(WorkflowTestRunTest.class); FewsInstance.init(TestSupport.getInputFile()); TestSupport.setUp(); configDir = TestSupport.getInputFile("config"); relativeViewPeriod = new RelativePeriod(-100 * TimeUnit.DAY_MILLIS, TimeUnit.DAY_MILLIS); connection = TestSupport.createTestDatabase("test"); // create datastore dataStore = new TestDataStore(connection, configDir, coldStatesDir, cacheDir, time0); // select the workflowtest configuration file File configFile = TestSupport.getInputFile("testfiles/WFT_Test1.xml"); SystemActivityDescriptor descriptor = dataStore.getRuns().getSystemActivityDescriptors().add(SystemActivityType.OC); // the WorkflowTestRun is created here WorkflowTestRun testRun = new WorkflowTestRun(dataStore, descriptor); // run it testRun.run(configFile); .... |
Workflow test runs can be started from the command line. To do so one must configure a Region as they would for a Stand Alone system.
The required flags should be set when calling FEWS from the command line. This can be done conveniently with the simple DOS batch file below. Note that one should at minimum specify the root folder where the FEWS bin is stored, the regionHome directory, the patch, and the WorkflowTestRun file that is to be executed.
echo off set root=%1 set region_home=%2 set workflowtestrun=%3 start /wait %root%\bin\windows\Delft-FEWSc.exe -Dregion.home=%region_home% -DautoRollingBarrel=false -Xmx1024m -DoldPID=13096_1555070573358 -Djava.locale.providers=SPI,JRE -Dstart.time=1555070573676 -Djava.library.path=%root%\bin\windows -Wvm.location=%root%\bin\windows\jre\bin\server\jvm.dll -Wclasspath.1=%region_home%\sa_patch.jar -Wclasspath.2=%root%\bin\*.jar -Wmain.class=nl.wldelft.fews.system.workflowtestrun.WorkflowTestRun -Warg.1=%region_home% -Warg.2=%workflowtestrun% |
The normal startup script in linux systems is shown below:
#!/bin/sh # # Script to start Delft-FEWS # # One argument required: the name of the region directory # export JAVA_HOME=$(pwd)/jre/bin if [ "$1" = "" ]; then echo "Usage: $0 <region name>" exit fi if [ ! -d "bin" -o ! -d "$1" ]; then echo "Start the script in the directory holding the region directory" exit fi # # Assemble the list of jar files in the bin directory # cd bin base=`pwd` # Assemble the classes # classes="" for f in $base/*.jar ;do if [ "$classes" = "" ]; then classes="$f" else classes="${classes}:$f" fi done echo "Java runtime: ${JAVA_HOME:-/opt/java/bin}/java - should at least be 1.5" echo "Starting application ..." ${JAVA_HOME:-/opt/java/bin}/java -Xmx256M -Djava.library.path=$base \ -classpath "$classes" \ nl.wldelft.fews.gui.explorer.Application $1 # # Remote debugging: add the following lines to the above: # -Xdebug \ # -Xrunjdwp:transport=dt_socket,address=8000,suspend=y,server=y \ exit |
The stand-alone direct data access system (SA-DDA) is a stand-alone application where workflows/tasks are scheduled using Windows Task Scheduler. An automated stand-alone DDA application:
An impression of the IT-infrastructure, including the connections to (external) user clients is shown in the figure below.
This feature makes possible to update SA localDataStore (in Client SA) with a new one that has been exported by an another SA (Master SA)
This feature supports only firebird database.
Master SA exports local.fdb using exportArchiveModule, for example:
<exportSnapShot> <general> <archiveFolder>c:/localDataStoreSnapshot</archiveFolder> <zipExportedSnapShot>false</zipExportedSnapShot> <singularExport/> </general> <activities> <exportSnapShot> <areaId>NL</areaId> </exportSnapShot> </activities> </exportSnapShot> |
The option <singularExport/> should be used to overwrite local.fdb every time the exportArchiveModule is run. Also the option zipExportedSnapShot should be set to false, otherwise Client SA will not update.
Client SA should have option localDataStoreSnapshotDownload in the Explorer.xml , for example:
<localDataStoreSnapshotDownload> <file>c:/localDataStoreSnapshot/local.fdb</file> <downloadEnabled>true</downloadEnabled> </localDataStoreSnapshotDownload> |
Path configured in <file> should be the same as path configured in <archiveFolder> of exportArchiveModule. When localDataStoreSnapshotDownload configured, then an item ‘Load latest localDataStore snapshot’ appears in menu File. Using this menu item a new localDataStore can be ingested.
To make the users aware of the new localDataStore snapshot, there is a field “LDS” in the explorer status bar. This field is green if the localDataStore is up to date, or red if a new localDataStore snapshot is available . Also a notification appears when the Client SA is started and a new localDataStore snapshot is available:
“New localDataStore is available in ….. Do you want to update the current localDataStore ?"
To keep the Client and Master configs the same, localDataStoreSnapshotDownload can be configured also in Master SA, with downloadEnabled = false.
