Mocking generate from java class/file

[OzGhost]

Situation

• Unittest require a lot of mocking to be done.
• Most of the mocking is easy to write but it take too much time.

Expectation

• A solution that consume a class/file then generate sample mocking code for every external call, organize as a test file.
• The generated output just act as a sample that can be quickly copy the needed part.
• Target mocking framework can be either Mockito (for popularity) or jMockit (for execution speed).

Selected option:

• Input: a file (use parser to get info out of it)
• Output: Mockito syntax

[OzGhost]

v0.0.1:

• Support mock on injected fields
• Support mocks: when ... thenReturn when ... thenThrow doNothing ... when doThrow ... when
• Set up real values all case

Sample:

java -jar mockgen.jar /tmp/project/src/main/services/AddressService.java

Output on stdout:

when(addrDao.create(arg0, arg1, arg2, arg3)).thenReturn(out0);
when(addrDao.create(any(), any(), any(), any())).thenReturn(out0);
when(addrDao.delete(arg0)).thenThrow(ex0);
when(addrDao.delete(any())).thenThrow(ex0);
doNothing().when(addrDao).update(arg0);
doNothing().when(addrDao).update(any());
doThrow(ex0).when(addrDao).merge(arg0, arg1);
doThrow(ex0).when(addrDao).merge(any(), any());
