Thanks @hvanhovell , the major changes is `SQLQueryTestSuite.scala`:
```scala
private def listTestCases(): Seq[TestCase] = {
- listFilesRecursively(new File(inputFilePath)).map { file =>
+ listFilesRecursively(new File(inputFilePath)).flatMap { file =>
val resultFile = file.getAbsolutePath.replace(inputFilePath,
goldenFilePath) + ".out"
val absPath = file.getAbsolutePath
val testCaseName =
absPath.stripPrefix(inputFilePath).stripPrefix(File.separator)
- TestCase(testCaseName, absPath, resultFile)
+ if (testCaseName.contains("typeCoercion")) {
+ TypeCoercionMode.values.map(_.toString).map { mode =>
+ val fileNameWithMode = mode + File.separator + file.getName
+ val newTestCaseName = testCaseName.replace(file.getName,
fileNameWithMode)
+ val newResultFile = resultFile.replace(file.getName,
fileNameWithMode)
+ TestCase(newTestCaseName, absPath, newResultFile, mode)
+ }.toSeq
+ } else {
+ Seq(TestCase(testCaseName, absPath, resultFile))
+ }
}
```
For a [type coercion
input](https://github.com/apache/spark/tree/v2.3.0-rc2/sql/core/src/test/resources/sql-tests/inputs/typeCoercion),
two results are generated in different mode(`default` and `hive`).
**For example**:
_input_:
sql/core/src/test/resources/sql-tests/inputs/typeCoercion/binaryComparison.sql
_results_:
sql/core/src/test/resources/sql-tests/results/typeCoercion/default/binaryComparison.sql.out
sql/core/src/test/resources/sql-tests/results/typeCoercion/hive/binaryComparison.sql.out
