Setup database

Setup the database content before each test to make tests repeatable.

Use separate and specific setup dataset for each test - setup exactly the data that is required by the test.
Avoid "kitchen-sink" single shared setup for all the tests - it quickly gets unmaintained as it is not obvious which data is used by which test (and which data is NOT used anymore) and becomes a major roadblock on tests refactoring.

Rows are inserted into the database in the order specified in the dataset. (Tables are deleted before that in the reverse order.)

Default @Setup annotation
When a test method or a test class is annotated with @Setup, the following files are located sequentially in the package of the class, the first file found wins:

• <test class name>.<test method name>.xml
• <test method name>.xml
• <test class name>.xml

Then a "clean insert" database operation is performed with the dataset located.

Example:

@Setup
public class MyTest {
  @Test
  public void test() {
  }
}

Specify dataset file names in @Setup
When the @Setup annotation contains file names of datasets, they are used to locate the datasets in the package of the test class and the "clean insert" database operation is performed with all such datasets located.

Example:

@Setup({ "setup-1.xml", "setup-2.xml" })
public class MyTest {
  @Test
  public void test() {
  }
}

Specify profile in @Setup
Use profile attribute of @Setup annotation to instruct Light Air to apply the datasets on the connection defined by the profile.
See the Profiles section in Configure Light Air for details on how to setup profiles.

Example:

@Setup(value = { "setup-1.xml", "setup-2.xml" }, profile = "oracle")
public class MyTest {
  @Test
  public void test() {
  }
}

Specify multiple @Setup annotations
Use @Setup.List annotation to define multiple @Setup annotations for the same test class or test method.

Example:

@Setup.List({
  @Setup("setup-h2.xml"),
  @Setup(value = "setup-hsql.xml", profile = "hsql"),
  @Setup(value = { "setup-ora-1.xml", "setup-ora-2.xml" }, profile = "oracle") })
public class MyTest {
  @Test
  public void test() {
  }
}

Empty row
Use "empty row", i.e. element with no attributes, to clean the table without inserting any rows.

Example:

<dataset>
  <my_table/>
</dataset>

Token @null - null value
Use @null to setup column to null value explicitly. (By omitting the column on the row you can also set it up to null value implicitly, unless there is a default value defined at the database level.)

Token @date - current date
Use @date to setup column to current date midnight value.
The current date value includes yyyy-MM-dd as in 2012-12-31.
The time part is set to midnight (00:00:00.000).

Token @time - current time
Use @time to setup column to current time value.
The current time value includes HH:mm:ss as in 23:59:58.
The date part is set to 1970-01-01. The milliseconds are set to 0 (zero).

Token @timestamp - current timestamp
Use @timestamp to setup column to current timestamp value.
The current timestamp value includes yyyy-MM-ddTHH:mm:ss.SSS as in 2012-12-31T23:59:58.123.

Modify the temporal tokens with a duration
You can modify the temporal tokens @date, @time and @timestamp by appending a sign (+ or -) and a duration in ISO 8601 format. This will move the time instant represented by the temporal token in the direction of the sing by the duration specified.

Examples:

• The bare token @date represents the last midnight.
• This @date+P1D represents the first following midnight.
• This @date-P1M represents the midnight one month before the last one.
• This @date+PT12H represents noon today.
• This @timestamp+PT1H represents one hour in the future.
• This @timestamp-P2Y3M4DT5H6M7S represents 2 years, 3 months, 4 days, 5 hours, 6 minutes and 7 seconds in the past.

Token @auto - generate unique value
Use @auto as a column value to have the actual value generated automatically.
The value is guaranteed to be unique, with the obvious exception of boolean columns.

Example:

<dataset>
  <user id="@auto" email="@auto" name="@auto" password="@auto" version="@auto" />
  <user id="@auto" email="@auto" name="@auto" password="@auto" version="@auto" />
  <user id="@auto" email="@auto" name="@auto" password="@auto" version="@auto" />
</dataset>
