[HrayrMuradyan]

[HrayrMuradyan]

Input tests:

dataset:

• Should be a valid dataframe (pd.Dataframe object).
• dataset should not be empty
• dataset shouldn't contain too many observations and too many columns (There should a limit for both)

dataset_name:

• shouldn't be too long (a threshold should be assigned)

description:

• should be text

show_observations:

• should be string. Either "random", "head" or "tail".

show_n_observations:

• should be an integer. Bounded between 0 and the dataset length.

show_warnings:

• should be boolean

summarize_by:

• string with the following values: "table", "plot", "mix"

auto_cleaning:

• boolean

target_variable:

• string, should be present in the dataset.

output_file:

• string. Can contain .pdf and can omit it.

output_dir:

• string. If doesn't exist, create it.

Output tests:

• Check if the output was created
• Check if the output has .pdf format
• Check if the output was generated in the correct path
• Check if the output is readable
