Testing Jupyter Notebook Code with Code Pattern Checks
Code patterns allow you to search for specific snippets within code files. To use these with Jupyter Notebook, you should first look at the IPYNB notebook file in its JSON plain text format. You can see this by clicking the "Edit" button after selecting the file:
The code pattern must match the code in Jupyter notebook file.
Note that the code in the notebook file may not necessarily be what you see in the Jupyter notebook cell due to whitespaces, escaped characters, etc.
If the Jupyter notebook file contains the following for a specific cell:
"import pandas as pd\n",
You can ensure that the user has correctly imported the
.csvfile using the
pandaslibrary by using the following code pattern:
Note that, using the
pytestmethod of testing Jupyter Notebooks, you can simply execute the cell to ensure the library is loaded.
