I have followed the directions from this website (https://schuchert.wikispaces.com/FitNesse.Tutorials.0.Java) to the t, however I cannot get the code on FitNesse to run clean.

I am consistently getting the following exceptions:

|Create Programs Could not invoke constructor for CreatePrograms[0]

|House The instance decisionTable_1.setName. does not exist

Here is my code. I have ensured my classpath is correct. Thank you for your time and consideration - I am very frustrated and confused with this.

!contents -R2 -g -p -f -h
!define TEST_SYSTEM {slim}

!path fitnesse-standalone.jar

!define COLLAPSE_SETUP {true}
!define COLLAPSE_TEARDOWN {true}

!path Users/Julianne/src/fitnesse-tutorials/DVR/bin/
|import|
|com.om.example.dvr.fixtures|


!|Create Programs                                        |
|Name |Channel|DayOfWeek|TimeOfDay|DurationInMinutes|id? |
|House|4      |Monday   |19:00    |60               |$ID=|

Could not invoke constructor for CreatePrograms[0]

This error tells you that the test execution cannot find the fixture code in the classpath (accumulated from !path statements) that it launches.

It looks like you are giving a relative path here

!path Users/Julianne/src/fitnesse-tutorials/DVR/bin/

Given that you are running on Mac OS, if you specify it without the preceding '/', it becomes a relative path from the location that you launch your server.

Another thing to check is that ensure right under .../bin you have com/om/example/dvr/fixtures and the .class files are there.

On a side note: A useful trick to check the resulted classpath for the test execution is to add the following block to somewhere on test page (or included setup page)

|script     |java properties|
|show   |property   |java.class.path|

try to edit the root page and define classpath and variables there: i.e. http://localhost:8090/root

#!***> Classpath

!path ${java.class.path}
!define TEST_SYSTEM {slim}
!define COLLAPSE_SETUP {true}
!define COLLAPSE_TEARDOWN {true}

  • it does not matter where you put the `!path` statement. It will only affect the sequence in the final generated classpath string if the !path is in a subpage (behind) or on a root page (in the front). – Xiawei Zhang Nov 30 '15 at 12:55

For me it worked when I added the class package name in the content.txt under SetUp folder so somewhat similar structure would be there to setup classpath for the test.

This error occurred because of missing class file or jar file in the path.

Try using below in the same test page rather than in setup page or root page:

!define TEST_SYSTEM {slim}
!path target/*.jar
!path lib/*.jar

where,

targer/*.jar = For maven project only after mvn clean install.

I struggled with this same error for a few days. I found that I was including too much information in my !path on the fitnesse page. I was including information which was already in my JAVA "package" statement.

If the class is within a package provide the path to the folder where the package starts.

for example, my CreditsForPayment.Class includes "package jukebox.fixtures;". The complete path to my class is: C:\Users\Brandon\IdeaProjects\untitled\out\production\untitled\jukebox\fixtures\CreditsForPayment.Class

, but in order for Fitnesse to properly find my class, I must use the path.

C:\Users\Brandon\Ideaprojects\untitled\out\production\untitled

with

|import|

|jukebox.fixtures| in my Fitnesse page.

Then you can go ahead with calling the class.

!|CreditsForPayment|

|payment|credits?|

|1|4|
