## Dataset Description |
|
Microsoft created the methods2test dataset, consisting of Java Junit test cases with their corresponding focal methods. |
|
It contains 780k pairs of JUnit test cases and focal methods which were extracted from a total of 91K Java open-source projects hosted on GitHub. |
|
|
|
This is a smaller subset of the assembled version of the methods2test dataset. |
|
It provides convenient access to the different context levels based on the raw source code (e.g. newlines are preserved). The test cases and associated classes are also made available. |
|
The subset is created by randomly selecting only one sample from each of the 91k projects. |
|
|
|
The mapping between test case and focal methods is based on heuristics rules and Java developer's best practice. |
|

|
## Focal Context |
|
- fm: this representation incorporates exclusively the source |
|
code of the focal method. Intuitively, this contains the most |
|
important information for generating accurate test cases for |
|
the given method. |
|
- fm+fc: this representation adds the focal class name, which |
|
can provide meaningful semantic information to the model. |
|
- fm+fc+c: this representation adds the signatures of the constructor methods of the focal class. The idea behind this |
|
augmentation is that the test case may require instantiating |
|
an object of the focal class in order to properly test the focal |
|
method. |
|
- fm+fc+c+m: this representation adds the signatures of the |
|
other public methods in the focal class. The rationale that motivated this inclusion is that the test case may need to |
|
invoke other auxiliary methods within the class (e.g., getters, |
|
setters) to set up or tear down the testing environment. |
|
- fm+fc+c+m+f: this representation adds the public fields of |
|
the focal class. The motivation is that test cases may need to |
|
inspect the status of the public fields to properly test a focal |
|
method. |
|
|
|
The test case along with the class name is also provided for each focal context. |
|
|
|
![image/pdf](https://huggingface.co/datasets/fals3/methods2test/resolve/main/focal_context.png) |
|
|
|
The different levels of focal contexts are the following: |
|
``` |
|
fm: focal method |
|
fm+fc: focal method + focal class name |
|
fm+fc+c: focal method + focal class name + constructor signatures |
|
fm+fc+c+m: focal method + focal class name + constructor signatures + public method signatures |
|
fm+fc+c+m+f: focal method + focal class name + constructor signatures + public method signatures + public fields |
|
``` |
