How can I mock incremental behavior in Code Repository?

I want to test incremental behavior in Foundry for testing and learning purposes. How can I mock the behavior of an incremental transforms generating data on each run ?

Here’s a good snippet to mock an incremental behavior:

Building this transform will keep “appending” fake data, which let you test schedules, downstream transforms, etc.

# from pyspark.sql import functions as F
from transforms.api import transform, Input, Output, configure, incremental
from pyspark.sql import Row
from pyspark.sql import functions as F
from pyspark.sql import types as T
import logging
import time
import json
log = logging.getLogger(__name__)

@incremental(semantic_version=1)
@configure(profile=["KUBERNETES_NO_EXECUTORS"])
@transform(
    out=Output("<rid>"),
)
def compute(ctx, out):
    # HERE TODO : API Calls, custom processing, generate a dataframe and save it or save files directly to the output dataset
    out.write_dataframe(get_dataframe(ctx))


def get_dataframe(ctx):
    # Define the schema of the dataframe
    schema = T.StructType([
        T.StructField("name", T.StringType(), True),
        T.StructField("age", T.IntegerType(), True),
        T.StructField("city", T.StringType(), True)
    ])

    # Create a list of rows
    data = [("Alice", 25, "New York"),
            ("Bob", 30, "San Francisco"),
            ("Charlie", 35, "London")]

    # Create a PySpark dataframe
    df = ctx.spark_session.createDataFrame(data, schema=schema)

    return df
