Increase automatic test case generation

I was writing about 2 things in the past: state transition based testing and automatic testcase generation. This is actually about 2 complementary test design techniques: state transition diagrams and decision tables respectively (I do not want to write about details of these techniques now – this is a subject for separate post I hope to write in the future). In the latter post I showed how to automate test case generation for decision tables, the goal for today is to show how to start automation when diagram is the starting point.

Combinatorial nature of a problem can be expressed as decision table and can be translated into xml for TCases application to process it and produce output which contains optimal set of test cases (automatic testcase generation). However, the most general way to analyze application under test is the state transition diagram. I already showed how to use this technique in order to achieve the coverage but I showed only the manual approach. Still, we need automatic test case generation!

When diagram is in use, the trouble begins: how to process it automatically? How to generate set of test cases from a diagram? It was quite a while until I came up with some reasonable solution.

I recently thought I could try TCases for this purpose. Although this is meant to identify variables and its values, if transitions of the diagrams could be considered as variables and their dependencies were described in TCases xml input file, I could get valid set of transitions and each transition would be used at least once in basic coverage setting.

Practical example

Create model

Let’s use the same problem as in state transition based testing. We want to test if Notepad is working when switching between tabs and changing text direction inside each of them as well as writing text in each of them. This is very simplified model but it is enough to ilustrate the concept. The state transition diagram looks like this:

Now, it is required to translate it into XML representation which will be parsable for TCases (I was writing about TCases HERE). This is it:

INPUT is the state name, VAR is the transaction.

COMMAND in HAS elements contains domain language sentences which are executable after simple processing by domain language generator.

WHEN elements describe needed dependencies to allow only valid combinations of transactions.

EXPECTED in HAS elements shows we just assert if Notepad GUI is visible after each set of transactions is run.

There is one problem with this file: in line 16 we need to give all the sequence of transactions needed to reach SELECT2TAB as TAB_1_IS_SELECTED state has 2 outgoing transactions. This shows there is a disadvantage of modeling the diagram in this way if there are states using very many transactions.

Generate executable test case

After generator is run, the set of test cases is produced. Generator reference is

com.passfailerror.testcases_generator

1	com.passfailerror.testcases_generator

The link to the source code is shown at the end of this post if you are interested.

When using basic coverage which is 1-tuple coverage it will mean each transaction will be used at least once. Because each transaction is marked as TRUE or FALSE (decision about transaction is valid when dependencies are met) the set of transactions will contain both TRUE and FALSE: it means in the generated test case there can be all valid transactions but also part of them as well. This is 1-tuple coverage:

With generated test cases (tc3 is missing as it consists of FALSE values only and generator wisely skips such test cases):

@Test
public void testStates_tc0(){
WHEN().tab(new2).isOpened().
WHEN().tab(new2).isClosed().
THEN().notepad().guiIsVisible();

}

@Test
public void testStates_tc1(){
WHEN().tab(new1).isWritten("tab1text").
WHEN().textDirectionIsChanged(RTL).
WHEN().textDirectionIsChanged(LTR).
THEN().notepad().guiIsVisible();

}

@Test
public void testStates_tc2(){
WHEN().tab(new2).isOpened().WHEN().tab(new1).isSelected().WHEN().tab(new2).isSelected().
WHEN().tab(new2).isWritten("tab2text").
WHEN().textDirectionIsChanged(RTL).
WHEN().textDirectionIsChanged(LTR).
THEN().notepad().guiIsVisible();

}

Now, when creation process of test cases is automated it is very easy to increase the coverage. This is 2-tuple coverage:

Sum up

Even if not perfect this is a solution to automatically generate test cases from state transition diagram. Together with automatic test case generation for combinatorial problems described by decision tables it is very solid approach to quickly achieve optimal coverage and thus assure quality in the application under test.
