Utility for creating dummy data for Scala tests
## Installation
Add the following line to your build.sbt file:
```sbt
libraryDependencies += "com.alejandrohdezma" %% "dummy" % "0.6.1" % Test
```
## Usage
Create a new `dummy` object and add some dummy cases you want to use:
```scala
import com.alejandrohdezma.dummy.Dummy
import java.util.UUID
import scala.util.Random
object dummy {
val dogs = Dummy(UUID.randomUUID())
val cats = Dummy.withName(name => s"${Random.alphanumeric.take(5).mkString}-$name")
val dates = Dummy.fromNaturalLanguageDate()
}
```
And then use it in your tests with any value you want (uses
[Scala's Dynamic](https://www.scala-lang.org/api/2.13.3/scala/Dynamic.html)
under the hood):
```scala
dummy.dogs.snoopy
// res0: UUID = 8e8cae16-a1e0-4ced-bb30-70b962c9d08a
dummy.dogs.`santa's-little-helper`
// res1: UUID = d6829a6f-b34f-429f-ae44-04c0fa17ba7a
dummy.cats.garfield
// res2: String = "uNaql-garfield"
dummy.cats.sylvester
// res3: String = "kKVkq-sylvester"
dummy.dates.`3 days ago`
// res4: java.time.Instant = 2024-03-11T12:09:04.354561159Z
dummy.dates.yesterday
// res5: java.time.Instant = 2024-03-13T12:09:04.354902729Z
```
The key of these generators is that values are cached, so if we try to use the
same "key" twice, it will give us the same value:
```scala
dummy.dogs.snoopy
// res6: UUID = 8e8cae16-a1e0-4ced-bb30-70b962c9d08a
dummy.dogs.`santa's-little-helper`
// res7: UUID = d6829a6f-b34f-429f-ae44-04c0fa17ba7a
dummy.cats.garfield
// res8: String = "uNaql-garfield"
dummy.cats.sylvester
// res9: String = "kKVkq-sylvester"
dummy.dates.`3 days ago`
// res10: java.time.Instant = 2024-03-11T12:09:04.354561159Z
dummy.dates.yesterday
// res11: java.time.Instant = 2024-03-13T12:09:04.354902729Z
```
### Accessing the cache
You can access the internal `Dummy` cache to see the values in
store.
```scala
dummy.dogs.cache.all
// res12: Map[String, UUID] = Map(
// "snoopy" -> 8e8cae16-a1e0-4ced-bb30-70b962c9d08a,
// "santa's-little-helper" -> d6829a6f-b34f-429f-ae44-04c0fa17ba7a
// )
dummy.cats.cache.all
// res13: Map[String, String] = Map(
// "sylvester" -> "kKVkq-sylvester",
// "garfield" -> "uNaql-garfield"
// )
dummy.dates.cache.all
// res14: Map[String, java.time.Instant] = Map(
// "yesterday" -> 2024-03-13T12:09:04.354902729Z,
// "3 days ago" -> 2024-03-11T12:09:04.354561159Z
// )
```
There are also available some convenient methods to get values from the cache
based on their name or value:
```scala
dummy.dogs.withName("snoopy")
// res15: UUID = 8e8cae16-a1e0-4ced-bb30-70b962c9d08a
dummy.cats.withValue(_.endsWith("garfield"))
// res16: String = "uNaql-garfield"
```
