-This piece of code creates a rialto transformation called *my_job*, which is then callable by the rialto runner. It first sources the *my_datasource* and then runs *my_job* on top of that datasource.

-### job naming / outputs
-The rialto runner creates a final table according to the job's name. Therefore, we do support 2 ways of creating jobs:
+This piece of code 
+1. creates a rialto transformation called *my_job*, which is then callable by the rialto runner. 
+2. It sources the *my_datasource* and then runs *my_job* on top of that datasource.
+3. Rialto adds VERSION (of your package) and INFORMATION_DATE (as per config) columns automatically.
+4. The rialto runner stores the final to a catalog, to a table according to the job's name.
+
+### Custom job names
+Note, that by default, the rialto job name is your function name. To allow more flexibility, we therefore allow renaming of the job:
 ```python
-@job("my_custom_name")
+@job(custom_name="my_custom_name")
 def f(...):
     ...
+```
+Just note that any *WeirdCaseNames* will be transformed to *lower_case_with_underscores*.
 
-@job
-def my_custom_name(...):
+### Disabling Versioning
+If you want to disable versioning of your job (adding package VERSION column to your output):
+
+```python3
+@job(disable_version=True)
+def my_job(...):
     ...
 ```
-Up to you, both work. Just note that any *WeirdCaseNames* will be transformed to *lower_case_with_underscores*.
 
-### notes / rules
+These parameters can be used separately, or combined.
+
+### Notes & Rules
 The rules for the dependencies are fairly straightforward.
 Both **jobs** and **datasources** can only depend on *pre-defined* dependencies and other *datasources*. Meaning:
 * *datasource -> datasource -> job* is perfectly fine,
 * *datasource -> job -> datasource* will result in an error.
 
 Secondly, the jobs can, but **don't necessarily have to output** a dataframe.
-In case your job doesn't output a dataframe, your job will only return a bunch of rows, which will ensure that rialto notices that the job ran successfully.
+In case your job doesn't output a dataframe, your job will return an artificially-created, one-row dataframe, which will ensure that rialto notices that the job ran successfully.
 This can be useful in **model training**.
 
 Finally, remember, that your jobs are still just *Rialto Transformations* internally.
 Meaning that at the end of the day, you should always read some data, do some operations on it and either return a pyspark DataFrame, or not return anything and let the framework return the placeholder one.
 
+### Testing
+One of the main advantages of the jobs module is simplification of unit tests for your transformations. Rialto provides following tools:
+
+#### 1. Disabling Decorators
+
+Assuming we have a my_job.test_job_module.py module:
+```python3
+@datasource
+def datasource_a(...)
+    ... code ...
+
+@job
+def my_job(datasource_a, ...)
+    ... code ...
+```
+The *disable_job_decorators* context manager, as the name suggests, disables all decorator functionality and lets you access your functions as raw functions - making it super simple to unit-test:
+```python3
+from rialto.jobs.decorators.test_utils import disable_job_decorators
+import my_job.test_job_module as tjm
+
+# Datasource Testing
+def test_datasource_a():
+    ... mocks here ...
+    
+    with disable_job_decorators(tjm):
+        datasource_a_output = tjm.datasource_a(... mocks ...)
+        
+        ... asserts ...
+        
+# Job Testing
+def test_my_job():
+    datasource_a_mock = ...
+    ... other mocks...
+    
+    with disable_job_decorators(tjm):
+        job_output = tjm.my_job(datasource_a_mock, ... mocks ...)
+    
+        ... asserts ...
+```
+
+#### 2. Testing the @job Dependency Tree
+In complex use cases, it may happen that the dependencies of a job become quite complex. Or you simply want to be sure that you didn't accidentally misspelled your dependency name:
+
+```python3
+from rialto.jobs.decorators.test_utils import resolver_resolves
+import my_job.test_job_module as tjm
+
+def test_my_job_resolves(spark):
+    assert resolver_resolves(spark, tjm.my_job)
+```
+
+The code above fails if *my_job* depends on an undefined datasource (even indirectly), and detects cases where there's a circular dependency.

 ## <a id="loader"></a> 2.4 - loader
 This module is used to load features from feature store into your models and scripts. Loader provides options to load singular features, whole feature groups, as well as a selection of features from multiple groups defined in a config file, and served as a singular dataframe. It also provides interface to access feature metadata.
