Test Plan

Testing has been a part of our development process since day one. In the below sections, we what are test suite looks like and how we do automation -

Unit Tests

The Scanner and Parser portions of our compiler have been unit-tested. This was done so that we could be sure that the grammar codified in parser.mly was correct and outputted valid token on entering expression. To test this aspect, we used Menhir's --interpret flag to help us in testing. We created a Python program that takes a filename of tokens and generates a parse tree as outputted by Menhir.

Integration Tests

Once we started work on the remaining portions of the compiler (typechecker and codegen), we started writing integration tests to test the compiler end-to-end. Though we did not follow test-driven development in the usual style, we followed every feature commit with a thorough set of test cases. At the time of this writing, our compiler has 110 test cases which check each aspect of the compiler.

The following is a list of test-cases that we have written. As it can be seen, the names of the files have been kept descriptive for each feature they stand for. The sections below give a rough outline of a few test cases that were added in the test suite. The complete list of all the test cases are given below -

  • Literals

    • declaration of literals of all types.
    • assignment of literals.
    • ...
  • Functions

    • function declaration.
    • passing functions as arguments.
    • function calls.
    • recursive function calls.
    • generic functions
    • ...
  • Type System

    • annotating types explicitly
    • incorrect number of function arguments check.
    • incorrect type of function arguments.
    • type check of primary type expressions.
    • type check of composite type expressions.
    • ...
  • Maps

    • Adding an element gives a new map
    • Only a key of valid type should be allowed
    • Deleting the key from the map gives a new map
    • ...
  • List

    • List standard library functions work as expected
    • List concat works only with correct types
    • List equality on lists containing the same elements
    • ...

Automation

The test suite is automated and is written in OCaml. It works by simply looking at format of the jsjs file, compiles it and finally runs it with Node.js. If the file starts with pass the test-runner expects the code to compile and produce output as given in the corresponding .out file. Instead, if the test starts with pass, the file is expected to not compile and generate a warning message as given in the corresponding output file.

Here's a sample output of the test-cases -

    All testcases complete.
    Total Testcases : 110
    Total Passing   : 110
    Total Failed    : 0
    Execution time  : 0.123073s

Lastly, we also have continuous integration with Travis CI setup that automatically checks and runs all our test cases whenever a commit is pushed or a pull-request is opened on our repository.

GCD

Below is a example codegen output of the GCD program written in JSJS.

JSJS ->

val gcd = /\(a, b) => {
  if a == b then a
  else {
    if a > b
    then gcd((a - b), b)
    else gcd((b - a), a);
  };
};

print_num(gcd(12, 8));

Codegen ->

Testing Roles

Prakhar wrote the testing infrastructure for both unit and integration tests including test reporting, file structure, automation and Travis CI setup. Gaurang and Bahul worked on writing out test cases for the type-checker and lastly, Ayush worked on testing plan and testing out the standard library.
