This is brief manual for generating test scripts using Freemarker Template Engine

Freemarker Template Engine is an engine, created to process text files. It process only parts of text files, that are surrounded with special Freemarker directives. Everything else is copied directly to the output. So if the file does not contain Freemarker at all, that the result of the processing such file is an exact copy of this file.

Input:
gen 100 100 1 > 1 gen 100 100 2 > 2 gen 100 100 3 > 3 gen 100 100 4 > 4

Output:
gen 100 100 1 > 1 gen 100 100 2 > 2 gen 100 100 3 > 3 gen 100 100 4 > 4

Variables are created automatically during their first assignment. To assign a value to the variable #assign directive is used. To evaluate some expression with variables you should enclose it in ${} symbols.

Input:
<#assign i = 2/> <#assign j = 3/> gen ${i} ${j} ${i + j} ${i*j + i + j + 2} > $ <#assign i2 = i*i/> <#assign j2 = j*j/> gen ${i2} ${j2} > $

Output:
gen 2 3 5 13 > $ gen 4 9 > $

To iterate through the range of integers, #list directive is used. For example: Of course, loops can be nested. And all variables, that were declared previously, can be used inside.

Input:
<#assign maxN = 1/> <#list 1..5 as power> <#assign maxN = maxN * 10> <#list 1..5 as testNumber> generatorFile ${maxN} abacaba ${testNumber} > $ </#list> </#list>

Output:
generatorFile 10 abacaba 1 > $ generatorFile 10 abacaba 2 > $ generatorFile 10 abacaba 3 > $ generatorFile 10 abacaba 4 > $ generatorFile 10 abacaba 5 > $ generatorFile 100 abacaba 1 > $ generatorFile 100 abacaba 2 > $ generatorFile 100 abacaba 3 > $ generatorFile 100 abacaba 4 > $ generatorFile 100 abacaba 5 > $ generatorFile 1000 abacaba 1 > $ generatorFile 1000 abacaba 2 > $ generatorFile 1000 abacaba 3 > $ generatorFile 1000 abacaba 4 > $ generatorFile 1000 abacaba 5 > $ generatorFile 10000 abacaba 1 > $ generatorFile 10000 abacaba 2 > $ generatorFile 10000 abacaba 3 > $ generatorFile 10000 abacaba 4 > $ generatorFile 10000 abacaba 5 > $ generatorFile 100000 abacaba 1 > $ generatorFile 100000 abacaba 2 > $ generatorFile 100000 abacaba 3 > $ generatorFile 100000 abacaba 4 > $ generatorFile 100000 abacaba 5 > $
