JS

module	function	descrption
asserts	assertThrowsAsync(action, msg)	checks the async function action() thrown with message msg
asserts	assertRoughlyEqualValues(expected, actual, relativeDiff)	checks the expected value is equal to actual value with relativeDiff precision
utils	timeIncreaseTo(seconds)	increases blockchain time to seconds sec
utils	trackReceivedToken(token, wallet, txPromise, ...args)	returns amount of token which recieved the wallet in async method txPromise with arguments args

utils	signMessage(signer, messageHex)	signs messageHex with signer and patchs ganache's signature to geth's version
utils	countInstructions(txHash, instruction)	counts amount of instruction in transaction with txHash hash
profileEVM	profileEVM(txHash, instruction, optionalTraceFile)	the same as the countInstructions() with option of writing all trace to optionalTraceFile
profileEVM	gasspectEVM(txHash, options, optionalTraceFile)	returns all used operations in txHash transaction with options and their costs with option of writing all trace to optionalTraceFile

UTILS

Docify

Generates documentation in markdown format from natspec docs

Usage

Add to package.json file solidity compiler version and shortcut to run command

devDependencies section

"solc": "0.8.12",

scripts section

"docify": "npx solidity-utils-docify"

...

Test documentation generator (test-docgen)

Script generates documentation for tests in markdown format. Give descriptions for describe and it sections and build documentation using these descriptions.

Example

Test described as shown below

// Test suite
describe('My feature', function() {
    // Nested test suite 
    describe("My subfeature", function() {
        /*
            **Test case 1**
            Test case should work
         */
        it("My case", function() {
        // code here
        })
    })
})

will generated the following output

# My feature

Test suite

## My subfeature

Nested test suite 

### My case

**Test case 1**
Test case should work

Installation

• Before use install documentation parser

yarn add acquit --dev

• Optionally configure script for default usage. Add to script section in package.json

"test:docs": "npx test-docgen"

• Optionally configure script for generating test list only. Add to script section in package.json

"test:docs": "npx test-docgen -l"

Usage

If script configured

yarn test:docs

or

npx test-docgen

Available parameters

Options:
  -i, --input <input>      tests directory (default: "test")
  -x, --exclude [exclude]  exclude directories and files. omit argument to exclude all subdirectories (default: false)
  -o, --output <output>    file to write output (default: "TESTS.md")
  -c, --code               include code (default: false)
  -l, --list               list tests only, do not include description (default: false)
  -d, --debug              debug mode (default: false)
  -h, --help               display help for command

Examples

Generate docs with default input and output

npx test-docgen

Generate docs for files in folders tests/mocks and tests/utils

npx test-docgen -i "tests/mocks;tests/utils"

Exclude from docs file test/mock-exclude.js and test/utils folder

npx test-docgen -x "tests/mock-exclude.js;tests/utils"

Generate list of tests only

npx test-docgen -l
