Peter Dürr 305a95aef9 Integrate Python-based tests and benchmark into Travis 
* Unfortunately, due to the SWIG dependency, we need sudo to install on
  Travis (conflicts when adding with debian-sid source prevent using addons)
  which means we cannot use the container-based infrastructure anymore.
* Building the Python bindings requires g++5 (at least with -Werr set).
* When building the Python bindings on Travis, the numpy includes are not found
  by cmake, so they have to be added separately by running a Python process with
  `numpy.get_include()`
* The build script now (somewhat clumsily) depends on the RUN_PYTEST environment
  variable. If it is set to anything other than "", it will make the tests and
  run tests and benchmarks
 2017-08-14 12:02:03 +02:00
Peter Dürr 15c8c24418 Fix time units on plots 
* Time in plots was of by a factor of 1e3 due to wrong conversion from us.
 2017-08-14 12:02:03 +02:00
Peter Dürr b29067a188 Better handle Python dependencies 
* Add requirements.txt file with required Python packages
* Read requirements.txt from CMakeLists.txt to check dependencies and alert the
  user if necessary.
 2017-08-14 12:02:03 +02:00
Peter Dürr bb5719a0da Add Python wrapper to ecl and use it to test functionality 
* Add SWIG interface definition (and external numpy interface) to ecl classes
* Add section in CMakeLists.txt to build Python bindings and execute
  Python-based tests
* Write (property-based) tests that show the basic functionality of the Python
  bindings and the EKF (using pytest and hypothesis libraries)
* Write minimal benchmark for the EKF update (using benchmark plugin for pytest)
* Add plotting utilities to analyze tests
* Add lint script to keep the Python scripts clean
 2017-08-14 12:02:03 +02:00
Peter Dürr 5988900044 Add getters for a few private variables of the EstimatorInterface 
* For testing it is useful to have access to more internal states
* For the same reason I also promote the const FILTER_UPDATE_PERIOD_MS to
  public
 2017-08-14 12:02:03 +02:00
Peter Dürr a2ed0a76f9 Make the destructor of EstimatorInterface virtual 
* This is a sane choice (and should arguably always be done for classes with
  virtual methods to avoid undefined behavior)
* It is required for wrapping the EstimatorInterface with SWIG (without virtual
  destructor, deriving from the EstimatorInterface leads to
  -Werror=delete-non-virtual-dtor).
