| ## 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. |
| More information can be found here: |
| - [methods2test Github repo](https://github.com/microsoft/methods2test) |
| - [Methods2Test: A dataset of focal methods mapped to test cases](https://arxiv.org/pdf/2203.12776.pdf) |

| ``` |
|
|
| ## 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. |
|
|
|  |
|
|
| 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 |
| ``` |
