我有一个合约的函数,它在每次调用时发出事件。
我希望在每个通过的测试上发出一个事件,以下是一些测试:
it("should emit Error event when sending 5 ether", function(done){
var insurance = CarInsurance.deployed();
insurance.send({from: accounts[0], value: web3.toWei(5, 'ether')}).then(done).catch(done);
});
it("should emit Error event when sending 5 ether", function(done){
var insurance = CarInsurance.deployed();
insurance.send({from: accounts[0], value: web3.toWei(5, 'ether')}).then(function(txHash){
assert.notEqual(txHash, null);
}).then(done).catch(done);
});
it("should emit Error event when sending 5 ether", function(done){
var insurance = CarInsurance.deployed();
insurance.send({from: accounts[0], value: web3.toWei(5, 'ether')}).then(function(done){
done();
}).catch(done);
});
结果是:
1) should emit Error event when sending 5 ether
Events emitted during test:
---------------------------
Error(error: Must send 10 ether)
---------------------------
✓ should emit Error event when sending 5 ether (11120ms)
✓ should emit Error event when sending 5 ether (16077ms)
3 passing (51s)
1 failing
1) Contract: CarInsurance should emit Error event when sending 5 ether:
Error: done() invoked with non-Error: 0x87ae32b8d9f8f09dbb5d7b36267370f19d2bda90d3cf7608629cd5ec17658e9b
您可以看到唯一记录的失败。
任何想法 ?
谢谢
您将 tx 哈希值传递给 did() 函数。我认为问题出在:
insurance.send({from: accounts[0], value: web3.toWei(5, 'ether')}).then(done).catch(done);
将其更改为:
insurance.send({from: accounts[0], value: web3.toWei(5, 'ether')}).then(function() { done(); }).catch(done);
测试事件:
it("should check events", function(done) {
var watcher = contract.Reward();
// we'll send rewards
contract.sendReward(1, 10000, {from: accounts[0]}).then(function() {
return watcher.get();
}).then(function(events) {
// now we'll check that the events are correct
assert.equal(events.length, 1);
assert.equal(events[0].args.beneficiary.valueOf(), 1);
assert.equal(events[0].args.value.valueOf(), 10000);
}).then(done).catch(done);
});
