Testing environment form WAVES blockchain
How to ?
Import package and write typescript/javascript code, interacting with waves blockchain. Package contains all global type definitions.
Example using mocha test runner
import '@waves/js-test-env';
env.API_BASE = "http://localhost:6869/";
env.CHAIN_ID = "R";
env.SEED = "waves private node seed with waves tokens";
describe('My first test suite', () => {
const wvs = 10 ** 8;
before(async function () {
this.timeout(0);
await setupAccounts({foo: 0.001 * wvs, bar: 0.001 * wvs});
});
it('Assertions', async function () {
const ttx = transfer({amount: 100000000000000, recipient: address()}, accounts.foo)
expect(ttx.proofs.length).to.equal(1)
await expect(broadcast(ttx)).rejectedWith()
})
// And define tests inside suites
// As you can see, we can use async functions to write async tests. sync functions have default timeout = 20s
it('Aks balance and height', async function () {
// You can set timeout. If you set it to zero, test won't finish untill function resolves
this.timeout(0);
// You can ask balance or currentHeigh
const b = await balance();
const h = await currentHeight();
// Console methods avalilable in test. Everything will be printed in repl
console.log(b, h)
})
it('Assertions', async function () {
const ttx = transfer({amount: 100000000000000, recipient: address()}, accounts.foo)
// Synchronous assertion
expect(ttx.proofs.length).to.equal(1)
// Async assertion. Expect broadcast to fail
await expect(broadcast(ttx)).rejectedWith()
})
})
Here you can find list of all globally available functions for ride test environment and REPL
Keep in mind that by default, if not passed, chainId
, seed
and nodeUrl
are taken from your test env configuration file (or Web IDE settings)
