Unit testing is a process where u would be testing ur
application or mapping by taking sample data to check if it
satisfies the business rules.

Answer / sri ram

You can do unit testing by testing your mapping
1.develop the mapping,take target as a .csv file(if the
target db location is remote)
2.give some input satisfying business rules
3. check whether the output is generated appropriately

Answer / shaik

Unit Testing is one of the testing process to provide some
sample data (hard coded data some times) to ensure your
logic is working as expected.
Talking Unit Testing specific to Informatica this is how I
did :
1. Generate a reference table from a .csv file on
Informatica Analyst.
2. Generate a profile using this Reference table( when ever
a reference table is creared a corresponding sql table is
created in the provided db during configuration)
3. Apply your rule (mapplet) on your profile and check if
you get the expected results.
4.You can add /remove data in the reference table to check
various scenarios.

If informatica has its scheduler why using third party scheduler?

generate Unique sequence numbers for each partition in session with Unconnected Lookup ? Hi All, Please help me to resolve the below issue while Applying partitioning concept to my Session. This is a very simple mapping with Source, Lookup , router, and target. I need to Lookup on the target and compare with the source data, if any piece of data is new then Insert, and If any thing change in the existed data then Update. while Inserting the new records to the target table I'm generating sequence numbers with Unconnected lookup, by calling the maximum PK ID from the target table. The above flow is working fine from last one year. Now I wish to apply the Partitioning concept to the above floe(session) At source I used 4 pass through partitions.(For Each partition different filter conditions to pull the data from source) at Target I used 4 passthrough Partitions. it is working fine for some data, but for some rows for Insert Operation , it is throwing Unique key errors, because while Inserting the data it is generating the same sequence key twice. In detail : 1st row is coming from 1st partition and generated the sequence number 1 for that row. 2nd row is coming from 1st partition and generated the sequence number 2 for that row 3rd row is coming from the 2nd partition generated the sequence number 2 again for that row. (it must generate 3 for this row) the issue is becuase of generating the same sequence numbers twice for different partitions. Can any one Please help me to resolve this issue. While Applying partitions how can I generate a Unique Sequence numbers from Unconnected lookup for Each partitioned data. Regrads, N Kiran.
