Test Coverage Comparison
Tool for displaying code coverage according to different measures. Accepts a JS function and any combination of input variable values.
Example
Download repo from Github and manually copy the only file and add the only dependency to you project. The the following minimal example should display a statement coverage in percentile.
var testCodeCoverage = require("./index.js");
var code = `
function code(a, b, c) {
if(b<c){
if(a<c){
}
}
return;
}
`;
var testCases = [{a: 1,b: 1,c: 1}]
var tester = new testCodeCoverage.testCoverageComparison(code, testCases);
console.log(tester.statementCoverage());
Limitations
Currently only supports if blocks (no else blocks), logical operators and assigment operators.
Creating local scope variables by copying initial values is allowed. Such that "holder = a;" will cause a holder variable to be internally created.
TODO
Analysis targets
- Else blocks
- Increment operator
- While blocks
- Declaration keyword (var, let, const) support
- Algebraic operations (+ - * /) support
Algorithms
- Parser should be divided into smaller objects to allow finer grained output.
Testing
- Testing can be made more robust.
