Automatically generate test skeletons

[fregante]

This sounds like something complex, but perhaps you have better ideas.

ava-generate-tests could generate empty tests by statically analyzing the code, maybe behaving like a coverage tool by figuring out all the ways it could be run (e.g. isCool needs to be true to go in this if statement)

It can't actually build functional tests or figure out what they're supposed to output, but it could at least provide some sort of boilerplate to manually verify.

Example input.js:

export default function (sayHello) {
    if(sayHello) {
        return 'hello';
    }
}
export function strLength (str) {
    return str.length;
}

Example generated-tests.js:

import test from 'ava';
import camelizedModuleName, {strLength} from '.';

test('return undefined',t => {
    t.same(camelizedModuleName(), undefined);
});

test('return hello', t => {
    t.same(camelizedModuleName(true), 'hello');
});

test(TBD, t => { // "TBD" would be something the dev would have to replace
    t.same(strLength(TBD), TBD);
});

That would be really cool!

This is probably the best use case for Function.length if there ever was one.

i can look into working on something like this! have a couple semi similar projects that do some code/test generation
