7. FitNesse: The Details
Proprietary and Confidential

8. Downloading and Installing FitNesse
• Get the jar file and run it
– http://fitnesse.org/FrontPage.FitNesseDevelopment.DownLoad
– java –jar fitnesse.jar
• Or use the demo package:
• Get the file: on the svcc web site, attached to the session, or
on Github
• unzip the file and cd to lib dir
• start the fitnesse server: java -jar fitnesse.jar -p 8080
• open web browser and access http://localhost:8080
• click the link at the top for "CodeCampDemoPage“
• click the test button
Proprietary and Confidential

9. Setting your classpath
• Classpath statements
– Fitnesse needs to know where to find your fixture code
• This kind of error :
• Means you need to add this kind of statement: !path
– You should usually have this kind of stuff:
!contents
!path fitnesse.jar
!path C:/eclipse/fit_demo/eclipse-bin
!define TEST_SYSTEM {slim}
Proprietary and Confidential

10. Some Basic Test Tables
• Script table
– Good for procedural/workflow tests
– Flexible
– Use syntax: check, reject, ensure, show
• Decision table
– Good for data-driven tests
– Specific workflow
• Input methods  execute()  output methods
– Special method name interpretation
– Automatically calls reset() and execute() methods
• Query table
– Good for validating lists or tables of data
Proprietary and Confidential

11. Variable Usage
• Defining a static variable
– !define ROOT_URL {http://myserver.com}
– !define TESTUSER {testuser1@something.com}
• Storing a value in a variable on the fly
– Store variable: $X=
– Use variable: $X
• Using a variable
– To use this variable, enclose the variable name in ${ }
– Example:
• this: ${URL_ROOT}/context/index.html
• Will resolve to this: http://myserver.com/context/index.html
Proprietary and Confidential

12. Naming and Parameter passing
(Methods)
• (Un) Graceful Naming
– Automatically concatenates space-separated
words
• isHalloween  isHalloween()
• Is Halloween  isHalloween()
• is halloween  isHalloween()
• Is halloWeen  error
– When using methods with multiple
parameters, tries to intersperse method
name and paremeters
Proprietary and Confidential

13. Parameter passing (cont)
• Multi-parameter methods: isHalloween(int, String)
– |ensure|is|31|Halloween|October|
– |ensure|is Halloween|31||October|
• Single parameter: setCostume(String)
– |set costume|Clark Kent|
– |set|Clark Kent|costume|
• Constructors with parameters
– This constructor:
• public Halloween(String month, int day, String costume)
– Translates to this usage in a fitnesse table:
|Halloween|October|31|Cat|
|isHalloween?|get surprise?|
Proprietary and Confidential

14. UI Test Fixtures
• com.jbergin.HtmlFixture
– an adapter between FitNesse and HtmlUnit for use in
testing web applications
– Need to use !define TEST_SYSTEM {fit}
– http://htmlfixture.sourceforge.net/
– http://uebuild5:8084/FrontPage.UmaFitNesse.IngsecuritySuite.ConcurrentUserS
essionTest.AcceptanceTests
• webtest selenium
– an extension to FIT/FitNesse that uses Selenium Remote
Control. WebTest runs inside FitNesse.
– http://www.fitnesse.info/webtest
– http://uebuild5:8084/FrontPage.ReportsFitNesse.IsoformView.IsoformVi
ewWebTestSuite.IsoformViewWebTests

15. Real world usage is more complex
• What it looks like in the real (ie, complicated)world
– Session handling
• http://uebuild5.ingenuity.com:8084/FrontPage.UmaFitNesse.IngsecuritySuite.Concurren
tUserSessionTest.AcceptanceTests
– Static objects to provide data access
• http://uebuild5.ingenuity.com:8084/FrontPage.ContentserviceFitNesse.TestSuiteForCurrentContent.Ec
sMappingDataProviderTestSuite.P1Tests
– Complex checking of validity
• Unmarshaling JSON to check special conditions in a non
order dependent way
– http://uebuild5.ingenuity.com:8084/FrontPage.FaFitNesse.Test
SuiteForBaselineContentSpecific.FaProviderTestSuite.Execute
FaQuery.LfaQueryTestSuite.AcceptanceTests

16. Fixture code can get complicated
very quickly
public static boolean matchGFAResult(JSONObject jsonResult, GFAResult actualResult, boolean allowSubset,
boolean allowPvalueVerification,boolean geneCountVerification ,boolean allowZscoreVerification, boolean allowGeneEffectVerification) throws
JSONException {
JSONArray jsonItems = jsonResult.getJSONArray("items");
logger.info("expected item size = " + jsonItems.length());
logger.info("actual item size = " + actualResult.getFAResultItems().size());
if (jsonItems.length() > actualResult.getFAResultItems().size()) {
return false;
}
Map<String, GFAResultItem> itemMap = buildGFAResult(jsonItems);
if (allowSubset) {
for (Map.Entry<String, GFAResultItem> entry : itemMap.entrySet()) {
logger.info("Look for " + entry.getKey() + " in actual result");
GFAResultItem item = entry.getValue();
if (!containsItem(item, actualResult.getFAResultItems(), allowSubset, allowPvalueVerification,
geneCountVerification,allowZscoreVerification, allowGeneEffectVerification)) {
logger.info(item.getId().getAsString() + " is expected but couldn't be found in actual result");
return false;
}
}
} else {
return equalGFAItems(itemMap, actualResult.getFAResultItems(), allowSubset,allowPvalueVerification,
geneCountVerification,allowZscoreVerification, allowGeneEffectVerification);
}
return true;
}
private static boolean equalGFAItems(Map<String, GFAResultItem> itemMap,
Collection<GFAResultItem> actualResultItems, boolean allowSubset,
boolean allowPvalueVerification,boolean geneCountVerification ,boolean allowZscoreVerification, boolean allowGeneEffectVerification) {
if (itemMap.size() != actualResultItems.size()) {
return false;
}

17. Tips and tricks
• Search in your FitNesse wiki
• Use Includes
– Use includes as templates
– http://uebuild5.ingenuity.com:8084/FrontPage.IngtestFitNesse.StableSui
te.FaStableCompat
– http://uebuild5.ingenuity.com:8084/FrontPage.IngtestFitNesse.StableSui
te.ContentserviceStableCompat
• Comments
• Escaping special characters
– Start tables with ! to avoid unwanted interpretation of
graceful names, etc
– Surround special chars with !- -!
• Example: !-gobbledeygook ~!@#$%^&*(){}| as plain string-!
Proprietary and Confidential

18. Fancy fixtures and other nifty stuff
• JSON
– http://uebuild5:8084/FrontPage.MgFitNesse.TestSuiteForBaselineContentSpecific.GraphProviderTestSuite.GetNeighb
orhoodGraph.P1Tests
• Javascript validation
– http://localhost:8080/FrontPage.AutocompFitNesse.FunctionalTests.FitTests.GeneralTests.P1Tests
EVAL {
void execute(Parse row, JSONFixture fixture) {
Parse textCell = row.parts.more;// row.parts.more;
String evalText = textCell.text();
String text = fixture.page.getWebResponse().getContentAsString();
try {
jsEngine.eval("result = " + text + ";");
Object evaluationResult = jsEngine.eval(evalText);
if (evaluationResult instanceof Boolean) {
if ((Boolean)evaluationResult){ fixture.right(textCell);}
else {fixture.wrong(textCell); }
• Running tests based on tag
• Include: http://<host>:<port>/<suite path and test name>?responder=suite&suiteFilter=smoke,critical
• Exclude: http://<host>:<port>/<suite path and test name>?responder=suite&excludeSuiteFilter=NotRunningOnHudson

19. Test Variations
• What we’ve done with it that is different
– Use as execution framework for more
complex tests
– Extension of fitnesse server for data-driven
tests
– json fixture – pass in javascript
– Execution of Selenium tests
– Backwards Compatibility tests
Proprietary and Confidential

20. Best practices
• Test robustness
• Test organization
• Test readability
• Fixture design
– Tradeoff between flexibility and readability,
usability

22. Our Environment
• Multiple products (3 external, plus internal tools)
• Services-based
• Builds:
– Produce multiple artifacts, including a fitnesse package
– Example: A build of contentservice produces:
• contentservice-1.2.179886.clover.tar.gz
• contentservice-1.2.179886.tar.gz
• contentservicedb-1.2.179886.tar.gz
• contentservice_fitnesse-1.2.179886.tar.gz
– Fitnesse package contains wiki page tests, libs, config files

25. Lessons learned
• Adds a lot of value for our team
– Visibility into results and test history
– Accessible to non-technical people
– FitNesse is very good for visibility and straightforward
verification of data
• Not good for everything
– Easy to do it wrong
– Requires maintenance
– Not as flexible
• To do more, you have to get creative
• Fixture and test ownership needs to be a shared
responsibility
