Build Status

Remix-Tests

Tests for the Ethereum tool suite Remix

Installation

npm -g install remix-tests

Test structure

Example test file:

pragma solidity ^0.4.7;
import "remix_tests.sol"; // injected by remix-tests
import "./simple_storage.sol";

contract MyTest {
  SimpleStorage foo;
  uint i = 0;

  function beforeAll() {
    foo = new SimpleStorage();
  }

  function beforeEach() {
    if (i == 1) {
      foo.set(200);
    }
    i += 1;
  }

  function initialValueShouldBe100() public {
    Assert.equal(foo.get(), 100, "initial value is not correct");
  }

  function initialValueShouldBe200() public constant returns {
    return Assert.equal(foo.get(), 200, "initial value is not correct");
  }

}

Available special functions:

  • beforeEach() - runs before each test
  • beforeAll() - runs before all tests

Assert library

Available functions Supported types
Assert.ok() bool
Assert.equal() uint, int, bool, address, bytes32, string
Assert.notEqual() uint, int, bool, address, bytes32, string
Assert.greaterThan() uint, int
Assert.lesserThan() uint, int

Command Line

Remix-Tests will assume the tests will files whose name end with "_test.sol". e.g simple_storage_test.sol

Usage:

  • A directory with tests files remix-tests examples/
  • A test file remix-tests examples/simple_storage_test.sol

Library

Importing the library:

const RemixTests = require('remix-tests');

Running a single test object:

remixTests.runTest(contractName, contractObj, testCallback, resultsCallback)

params: testName - string name of the test testObj - web3.js 1.0 contract instance of the test testCallback(object) - called each time there is a test event. 3 possible type of objects:

  • { type: 'contract', value: '<TestName>', filename: '<test_filename.sol>' }
  • { type: 'testPass', value: '<name of testing function>', time: <time taken>, context: '<TestName>'}
  • { type: 'testFailure', value: '<name of testing function>', time: <time taken>, context: '<TestName>', errMsg: '<message in the Assert>' }

resultsCallback(object)

  • passingNum - number of passing tests
  • failureNum - number of failing tests
  • timePassed - time it took for all the tests to run (in seconds)

Running a set of tests given the sourcecode:

remixTests.runTestSources(contractSources, testCallback, resultCallback, finalCallback, importFileCb);

params: contractSources - object -> filename => { content: source } testCallback(object) - called each time there is a test event. 3 possible type of objects:

  • { type: 'contract', value: '<TestName>', filename: '<test_filename.sol>' }
  • { type: 'testPass', value: '<name of testing function>', time: <time taken>, context: '<TestName>'}
  • { type: 'testFailure', value: '<name of testing function>', time: <time taken>, context: '<TestName>', errMsg: '<message in the Assert>' }

resultCallback(err, object)

  • passingNum - number of passing tests
  • failureNum - number of failing tests
  • timePassed - time it took for all the tests to run (in seconds)

finalCallback(err) - called when all tests finish running. importCb(url, cb)
