// check balances
diff1 := account1.Balance - fromAccount.Balance
diff2 := toAccount.Balance - account2.Balance
require.Equal(t, diff1, diff2)
The above assertion succeeds most of time, but it really fails occassionaly. The cause is that we can't compare two float numbers directly.
Change the code as below:
// check balances
diff1 := account1.Balance - fromAccount.Balance
diff2 := toAccount.Balance - account2.Balance
require.LessOrEqual(t, math.Abs(diff1 - diff2), 1e-10)
