- Enceladus TestUtils
Hermes is an E2E testing tool created mainly for the use in ABSA OSS ecosystem but still provides some tools/utils that are usable in other projects and are quite generic. For more information, please look at our Hermes Github Pages.
Known to work with:
- Spark 2.4.4
- Java 1.8.0_191-b12
- Scala 2.11.12
- Hadoop 2.7.5
Spark job for the comparison of data sets. As it leverages spark, there are almost no limitations to data sources and size of the data.
Basic running example
spark-submit \ /path/to/jar/file \ --format <format of the reference and new data sets> \ --new-path /path/to/new/data/set \ --ref-path /path/to/referential/data/set \ --out-path /path/to/diff/output --keys key1,key2,key3
Datasets Comparison Usage: spark-submit [spark options] --class za.co.absa.hermes.datasetComparison.DatasetComparisonJob hermes.jar [options] --[ref|new]-format Format of the raw data (csv, xml, parquet,fixed-width, etc.). Use prefix only in case comparison of two different formats. Mandatory. --new-path|--new-dbtable Path to the new dataset or dbtable (jdbc), just generated and to be tested. Mandatory. --ref-path|--ref-dbtable Path to supposedly correct data set or dbtable (jdbc). Mandatory. --out-path. Path to where the `ComparisonJob` will save the differences. This will efectivly creat a folder in which you will find two other folders. expected_minus_actual and actual_minus_expected. Both hold parque data sets of differences. (minus as in is relative complement. Mandatory. --keys If there are know unique keys, they can be specified for better output. Keys should be specified one by one, with , (comma) between them. Optional. others Other options depends on selected format specifications (e.g. --delimiter and --header for csv, --rowTag for xml). For case comparison of two different formats use prefix ref|new for each of this options. For more information, check sparks documentation on what all the options for the format you are using. Optional. --help prints similar text to this one.
Other configurations are Spark dependant and are out of scope of this README.
Info File Comparison
Autm's (and it's derivatives) Info file comparison. Ran as part of the E2E Runner. Can be run as a plain old jar file.
Basic running example
java -jar \ /path/to/jar/file \ --new-path /path/to/new/data/set \ --ref-path /path/to/referential/data/set \ --out-path /path/to/diff/output
Currently runs both Standardization and Conformance of [Enceladus][enceladus] project on the data provided. After each, a comparison job is run to check the results against expected reference data.
This tool is planed for an upgrade in the nearest future to be a general E2E Runner for user defined runes.
Basic running example:
spark-submit \ /path/to/jar/file \ --menas-credentials-file /path/to/credentials/file \ --dataset-name <datasetName> \ --dataset-version <datasetVersion> \ --report-date <reportData> \ --report-version <reportVersion> \ --raw-format <rawFormat> --keys <key1,key2,...>
