What it is

(University of Sheffield COM3529 — SOFTWARE TESTING & ANALYSIS Assignment submission)

A Java tool for automatic test cases generating for a given class method. Tests are generated to maximize the code coverage. The final coverage and the generated test cases are saved in a JUnit tests file.

How it works

The tests are generated using a random search. However to achieve good results the program asks for information such as lower and upper bounds for int parameter to increase chances of produce high coverage tests.

The process consists of two parts: 1: automatic parsing the class and method given by user, 2: using the parsed and instrumented code to generate tests.

The program makes use of: javaparser https://javaparser.org/ and Java's Reflection https://www.oracle.com/technical-resources/articles/java/javareflection.html .

The following coverage criterias are calculated: Branch coverage, Condition coverage and correlated MCDC (Modified Condition Decision Coverage) coverage.

If the returned value is any of primitive types, String, or enum, an assertation is included to the test case. Note: It does not solve the Oracle problem - user still needs to decide if the returned value is correct.

How to use it

The program takes as input a Java class file with a method to be tested. The method needs to be public. Supported types for parameters: java.lang.Integer, java.lang.String, java.lang.Boolean and all primiteves excluding long. For other types null will be used.

0 Prerequisites

Java 11 or newer (was tested with versions 11.0.10 and 13.0.1)

Maven (was tested with Apache Maven 3.6.3)

Navigate to "/jautotest" and use mvn package

1 Prepare (parse) the file

Navigate to "/jautotest"
Given the class to be tested is CLASS_NAME, the method to be tested is METHOD_NAME, and the path to the file containing the class is PATH_TO_CLASS the command is:

mvn exec:java "-Dexec.mainClass=jautotest.app.Parse" "-Dexec.args='PATH_TO_CLASS/CLASS_NAME.java' 'CLASS_NAME' 'METHOD_NAME'" -e

(replace '/' delimiter to the correct one for your platform)

for example:

mvn exec:java "-Dexec.mainClass=jautotest.app.Parse" "-Dexec.args='../testfiles/BMICalculator.java' 'BMICalculator' 'calculate'" -e

Use

mvn compile

to make sure the parsed class is readable by the program.

2 Generate tests

The previous step needs to be fulfilled before generating tests.
Navigate to "/jautotest"
Given the class to be tested is CLASS_NAME, the method to be tested is METHOD_NAME:

mvn exec:java "-Dexec.mainClass=jautotest.app.GenerateTests" "-Dexec.args='CLASS_NAME' 'METHOD_NAME:'" -e

for example:

mvn exec:java "-Dexec.mainClass=jautotest.app.GenerateTests" "-Dexec.args='BMICalculator' 'calculate'" -e

Follow the instructions on the terminal

3 Run the generated tests

The test files are saved in /jautotest/src/test/java/jautotest/app/CLASS_NAMEMETHOD_NAMETest.java and can be run using mvn test.

Individual test files can be run using additional argument specifying its name (method name is capitalized) e.g.:

mvn test -Dtest=BMICalculatorCalculateTest

Problems, limitations, notes

Forbidden keywords

The tested method cannot have parameters with names: coveredBranches and coveredConditions .

The tested class cannot have variables with names: numberOfBranches, numberOfConditions and branchesPredicatesConditions.

In parsing process the tested class package is changed to "input", make sure it does not affect your code.

Multiple methods with the same name

The program takes the first public method with matching name. The problem arises if there are many methods with the same name. To specify which method should be chosen, its parameters need to be specified. In place of METHOD_NAME please put method declaration like: calculate(double weightInPounds, int heightFeet, int heightInches)

The method for parsing 'BMICalculator' 'calculate' method becomes:

mvn exec:java "-Dexec.mainClass=jautotest.app.Parse" "-Dexec.args='../testfiles/BMICalculator.java' 'BMICalculator' 'calculate(double weightInPounds, int heightFeet, int heightInches)'" -e

and generating tests:

mvn exec:java "-Dexec.mainClass=jautotest.app.GenerateTests" "-Dexec.args='BMICalculator' 'calculate(double weightInPounds, int heightFeet, int heightInches)'" -e

Note that the parameters are delimitered by commas and a maximum of 1 space!

Examples

Folder 'testfiles/' contains some simple programs that can be used as examples. (Some examples come from Phil McMinn https://mcminn.io/ as part of the course https://github.com/philmcminn/com3529-code)

BMICalculator

Parse:

mvn exec:java "-Dexec.mainClass=jautotest.app.Parse" "-Dexec.args='../testfiles/BMICalculator.java' 'BMICalculator' 'calculate'" -e

GenerateTests:

mvn exec:java "-Dexec.mainClass=jautotest.app.GenerateTests" "-Dexec.args='BMICalculator' 'calculate'" -e

A simple code which given 3 numbers calculates the BMI Type enum (UNDERWEIGHT, NORMAL, OVERWEIGHT, OBESE). This program supports enums in assertations so they are automatically added to the generated test case:

  public void test1() {
      // Object result = BMICalculator.calculate(29.1568199726307, 38, 1);
      Object result = input.BMICalculator.calculate(29.1568199726307, 38, 1, null, null, null);
      // remove the line above and uncomment upper one to test original code
      // assertTrue(result.equals(BMICalculator.Type.UNDERWEIGHT))
      assertTrue(result.equals(input.BMICalculator.Type.UNDERWEIGHT));
      // remove the line above and uncomment upper one to test original code
  }

No matter how many iterations the program will perform, the condition and thus cMCDC coverages will never reach 100%:

/*
Branch coverage: 100,00% (4/4)
Branch coverage - covered branches: [1, 2, 3, 4]

Condition coverage: 80,00% (8/10)
Condition coverage - covered conditions: [-5, -3, -1, 1, 2, 3, 4, 5]

Correlated MCDC coverage: 60,00% (3/5)
Correlated MCDC - covered conditions: [1, 3, 5]

Number of tests generated: 4
Test file generated automatically at 24-04-2021 18:47:14, please check the assertations.
*/

The obious reason is that conditions 2 (bmi >= 17.5) and 4 (bmi >= 25) can never be evaluated false.

SimpleBankAccount

Parse:

GenerateTests:

This example demonstrates that the program supports constructors and can test non static methods.

  @Test()

      input.SimpleBankAccount testedObject = new input.SimpleBankAccount("nXRO", 79, true);

      Object result = testedObject.withdrawCoins(-44, null, null, null);
