### Supported asserts:
| Assert | Description | Example | Return |
|-------------------------------------------------------------|-----------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------|-----------------------------------------------------|
| assert_true(condition, message=None) | Verify that condition is True. | soft_asserts.assert_true(a == b) | True if assertion passes, False if assertion fails. |
| assert_false(condition, message=None) | Verify that condition is False. | soft_asserts.assert_false(a == b) | True if assertion passes, False if assertion fails. |
| assert_equal(first, second, message=None) | Verify that first is equal to second. | soft_asserts.assert_equal(a, b) | True if assertion passes, False if assertion fails. |
| assert_not_equal(first, second, message=None) | Verify that first is not equal to second. | soft_asserts.assert_not_equal(a, b) | True if assertion passes, False if assertion fails. |
| assert_is(first, second, message=None) | Verify that first and second are the same object. | soft_asserts.assert_is(a, b) | True if assertion passes, False if assertion fails. |
| assert_is_not(first, second, message=None) | Verify that first and second are not the same object. | soft_asserts.assert_is_not(a, b) | True if assertion passes, False if assertion fails. |
| assert_is_none(obj, message=None) | Verify that obj is None. | soft_asserts.assert_is_none(a) | True if assertion passes, False if assertion fails. |
| assert_is_not_none(obj, message=None) | Verify that obj is not None. | soft_asserts.assert_is_not_none(a) | True if assertion passes, False if assertion fails. |
| assert_in(obj, container, message=None) | Verify that obj is in container. | soft_asserts.assert_in(a, [a, b, c]) | True if assertion passes, False if assertion fails. |
| assert_not_in(obj, container, message=None) | Verify that obj is not in container. | soft_asserts.assert_not_in(a, [b, c]) | True if assertion passes, False if assertion fails. |
| assert_is_instance(obj, cls, message=None) | Verify that obj is instance of cls. | soft_asserts.assert_is_instance(a, A) | True if assertion passes, False if assertion fails. |
| assert_is_not_instance(obj, cls, message=None) | Verify that obj is not instance of cls. | soft_asserts.assert_is_not_instance(a, B) | True if assertion passes, False if assertion fails. |
| assert_almost_equal(first, second, delta, message=None) | Verify that first is almost equal to second,<br/>and the different is equal or less to delta. | soft_asserts.assert_almost_equal(1.001, 1.002, 0.1) | True if assertion passes, False if assertion fails. |
| assert_not_almost_equal(first, second, delta, message=None) | Verify that first is not almost equal to second,<br/>and the different is more than delta. | soft_asserts.assert_not_almost_equal(1.001, 1.002, 0.00001) | True if assertion passes, False if assertion fails. |
| assert_raises(exception, method: Callable, *args, **kwargs) | Verify that method execution raise exception. | soft_asserts.assert_raises(TypeError, sum, 'a', 2) | True if assertion passes, False if assertion fails. |
| assert_raises_with(exception, message=None) | Verify that execution in 'with' block raise exception. | with soft_asserts.assert_raised_with(ValueError):<br/> raise ValueError(ERROR_MESSAGE_1) | |
In the end of each test, the soft asserts will be verified and the test will be marked as failed if any of the asserts failed.<br/>
To verify the soft asserts in the middle of the test, call `soft_asserts.assert_all()`.<br/>
<br/>
assert_all() will raise _AssertionError_ if any of the asserts failed.<br/>
#### Steps
Each testing section can be divided to steps.<br/>
The meaning of this is that if one of the asserts in a step failed,<br/>
then the step will be entered to list of failure steps and next test can be skipped<br/>
if it is depended on the failed step.<br/>
Example:
To make test be skipped if step failed, a custom marker should be created.
This is an example of such custom marker, but user can create its own custom marker.
In conftest.py file:
```python
import pytest
@pytest.fixture(autouse=True)
def run_before_test(request):
markers = request.node.own_markers
for marker in markers:
if marker.name == 'soft_asserts':
marker_params = marker.kwargs
soft_asserts = marker_params['soft_asserts']
skip_steps = marker_params['skip_steps']
for step in skip_steps:
if soft_asserts.is_step_in_failure_steps(step):
pytest.skip(f'Skipped because [{step}] failed.')
```
```python
import pytest
from nrt_pytest_soft_asserts.soft_asserts import SoftAsserts
soft_asserts = SoftAsserts()
STEP_1 = 'step_1'
STEP_2 = 'step_2'
def test_assert_with_steps():
soft_asserts.set_step(STEP_1)
# result is False
result = soft_asserts.assert_true(False)
# print False
print(result)
soft_asserts.set_step(STEP_2)
soft_asserts.assert_true(False)
# From this code section steps will not be attached to failure asserts
soft_asserts.unset_step()
soft_asserts.assert_true(False)
soft_asserts.assert_all()
@pytest.mark.soft_asserts(soft_asserts=soft_asserts, skip_steps=[STEP_1])
def test_skip_if_step_1_fail():
soft_asserts.assert_true(True)
@pytest.mark.soft_asserts(soft_asserts=soft_asserts, skip_steps=[STEP_2])
def test_skip_if_step_2_fail():
soft_asserts.assert_true(True)
```
#### Print error on each failed assert
Each assertion failure can be printed.<br/>
This can be done by adding logger or by adding a print method.<br/>
- In case a logger will be added to soft asserts, then logger.error(message) will be used.
- In case a print method will be added to soft asserts, then print_method(message) will be used.
- logger and print method cannot be added together.
#### Error format
`message [file_path: line_number] code_line`
#### logger example:
```python
import logging
from nrt_pytest_soft_asserts.soft_asserts import SoftAsserts
logger = logging.getLogger('test')
soft_asserts = SoftAsserts()
# logger will be used to print message after each assert fail.
soft_asserts.set_logger(logger)
def test_assert_true_fail():
i = 1
j = 2
# logger.error() will print messages to console for each assert that fails
soft_asserts.assert_true(i + j == 5)
# f'{i} is different from {j}' will be printed by logger.error() after assert will fail
soft_asserts.assert_equal(i, j, f'{i} is different from {j}')
soft_asserts.assert_all()
```
#### print method example:
```python
from nrt_pytest_soft_asserts.soft_asserts import SoftAsserts
def print_method(message):
print(message)
soft_asserts = SoftAsserts()
# print_method will be used to print message after each assert fail.
soft_asserts.set_print_method(print_method)
def test_assert_true_fail():
i = 1
j = 2
# print_method will print messages to console for each assert that fails
soft_asserts.assert_true(i + j == 5)
# f'{i} is different from {j}' will be printed by print_method after assert will fail
soft_asserts.assert_equal(i, j, f'{i} is different from {j}')
soft_asserts.assert_all()
```
