 ## Dataset Description
-Microsoft created the methods2test dataset, consisting of Java Junit test cases with its corresponding focal methods. 
-It contains 780k pairs of JUnit test cases and focal methods which were extracted from a total of 91K

+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 original authors validate the heuristics by inspecting a
-statistically significant sample (confidence level of 95% within 10%
-margin of error) of 97 samples from the training set. Two authors
-independently evaluated the sample, then met to discuss the disagreements. We found that 90.72% of the samples have a correct
