Writing a new eweasel test

Creating a new eweasel test is a very simple procedure which is described below.

Choosing the category

Here are the major categories of test:

• syntax
• incr
• melt
• freeze
• finalize
• exec
• ccomp
• term
• fixed

When creating a new test, choose the most appropriate category and append the incremented value for the last counter value for each category.

Writing the TCF file

A tcf would look like:

--| Copyright (c) 1993-2006 University of Southern California and contributors.
--| All rights reserved.
--| Your use of this work is governed under the terms of the GNU General
--| Public License version 2.
 
-- This is a test control file
 
test_name 	power-operator
test_description The power operator (infix "^") with INTEGERs, REALs and DOUBLEs
 
copy_sub 	Ace $TEST Ace
copy_raw 	test.e $CLUSTER test.e
compile_melted
compile_result 	ok
 
execute_work 	NONE 	exec_output1
execute_result 	ok
compare		exec_output1 output
 
test_end

This simply copy the Ace and test.e file over the test directory, compiles the project, execute the workbench executable and compare the output `exec_output1' with the stored output `output'.

Writing the ECF file

Usually its content would look like and for historical reason it has to be called Ace:

<?xml version="1.0" encoding="ISO-8859-1"?><system xmlns="http://www.eiffel.com/developers/xml/configuration-1-0-0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.eiffel.com/developers/xml/configuration-1-0-0 http://www.eiffel.com/developers/xml/configuration-1-0-0.xsd" name="test" uuid="D4B33796-B5BB-4a70-9646-147CE70640E7">
	<target name="test">
		<root cluster="root_cluster" class="test" feature="make"/>
		<option warning="true">
			<assertions precondition="true" postcondition="true" check="true" invariant="true" loop="true" supplier_precondition="true"/>
		<warning name="syntax" enabled="false"/></option>
		<precompile name="precompile" location="$PRECOMPILED_BASE"/>
		$EWEASEL_DOTNET_SETTING
		<library name="base" location="$ISE_LIBRARY\library\base\base.ecf"/>
		<cluster name="root_cluster" location="$CLUSTER\"/>
	</target>
</system>

Writing the Eiffel classes

The classes that make the test.

Writing the output file(s)

They contain the actual output of the program plus Execution completed when we expect a successful run, or Execution failed when we expect a failure.
