Tester

Evaluates one or more tests on a feature, and routes the feature according to the outcome of the test(s). The tests can consist of any FME-allowed operands.

Input Ports

Output Ports

Note that you can combine several tests into a single Tester transformer, and the features can be routed to Passed depending on the Pass Criteria below.

If you have several Tester transformers in sequence, consider using the TestFilter instead. This transformer allows you to create a series of tests with ‘named’ output ports for each result.

Parameters

Examples

Attribute Test Condition Result
x=abcd X Contains abcd Passed
x=a, Y=big X In Y Failed
X=100 X < 200 Passed
X=4E5 X=400000

Passed, if Mode set to Automatic

Failed, if Mode set to String

Examples where Mode could be set to Automatic or Numeric:

@Area() < 100

@Value(numLanes) > 2

Example where Mode could be set to String:

"Joe" = "Jerry"
