-These test executes 'unit-test'.
-
-To run please do the following:
-1. To run tests required installing some dependencies:
-    - pip3 install -r requirements.txt
-2. Set environment variable:
-    a. Required:
-        export PATH_TO_EXE=<path where nGraph unit-test locates>
-3. To run all tests:
-    a. cd folder where unit_test_executable.py locates
-    b. pytest --gtest_filter="*"
-4. To run exact test:
-    a. cd folder where unit_test_executable.py locates
-    b. pytest --gtest_filter="<your test name>"
-5. To get html report add "--html=report.html" to pytest cmd line
-    (but before install this module "pip install pytest-html")
-6.This test get result of opset1 operation (passed and failed) and also creates csv file 'nodes_coverage.csv' and
-    'nodes_coverage.html' after execution. Here you may find name of operations and its passrate and coverage
-    for several plugins.
-    Example:
-    Operation | GPU passed / total | CPU passed / total
-    Abs       | 1/2                | 1/2
-
-    Here operation 'Abs': 1 test of 2 passed on GPU and CPU
