Run the tests

Testing in flutter is interesting, our test code and business code run in two separate processes. The test code takes screen captures of the running business code to perform further predicate code. For more details under this mechanism please refer integration testing.

Here are the steps to start the tests:

  1. Downloading the executable binary file of Ontology from it's release page. The version used in the tests is ontology version v1.6.0-8-g754303c0
  2. Copying the test wallet located in file example/lib/test/common/wallet.dart and save it into file wallet.dat then put the saved wallet file and the Ontology binary from step 1 under the same directory.
  3. Starting Ontology node runs in test mode ./ontology --testmode --loglevel=1
  4. Starting the tests: cd example/ && flutter drive --target=test_driver/app.dart
