@ExperimentalTestApi
class FileTestStorage : PlatformTestStorage

A class that reads/writes the runner data using the raw file system.

This API is experimental and is subject to change or removal in future releases.

Summary

Public constructors
`FileTestStorage()`

Public functions
`Unit`	`addOutputProperties(properties: (Mutable)Map<String!, Serializable!>!)` Test output properties is not supported when raw file I/O is used.
`String!`	`getInputArg(argName: String!)` Implementation of input arguments that reads from InstrumentationRegistry.getArguments
`(Mutable)Map<String!, String!>!`	`getInputArgs()` Implementation of input arguments that reads from InstrumentationRegistry.getArguments
`(Mutable)Map<String!, Serializable!>!`	`getOutputProperties()` Test output properties is not supported when raw file I/O is used.
`InputStream!`	`openInputFile(pathname: String!)` Provides an InputStream to a test file dependency.
`InputStream!`	`openInternalInputFile(pathname: String!)` Provides an InputStream to an internal file used by the testing infrastructure.
`OutputStream!`	`openInternalOutputFile(pathname: String!)` Provides an OutputStream to an internal file used by the testing infrastructure.
`OutputStream!`	`openOutputFile(pathname: String!)` Provides an OutputStream to a test output file.
`OutputStream!`	`openOutputFile(pathname: String!, append: Boolean)` Provides an OutputStream to a test output file.

FileTestStorage()

fun addOutputProperties(properties: (Mutable)Map<String!, Serializable!>!): Unit

Test output properties is not supported when raw file I/O is used.

fun getInputArg(argName: String!): String!

Implementation of input arguments that reads from InstrumentationRegistry.getArguments

fun getInputArgs(): (Mutable)Map<String!, String!>!

Implementation of input arguments that reads from InstrumentationRegistry.getArguments

fun getOutputProperties(): (Mutable)Map<String!, Serializable!>!

Test output properties is not supported when raw file I/O is used.

An empty map is always returned.

fun openInputFile(pathname: String!): InputStream!

Provides an InputStream to a test file dependency.

Parameters
`pathname: String!`	path to the test file dependency. Should not be null. Can be either a relative or absolute path. If relative, the implementation will read the input file from the test apk's asset directory

Throws
`java.io.IOException`

fun openInternalInputFile(pathname: String!): InputStream!

Provides an InputStream to an internal file used by the testing infrastructure.

Parameters
`pathname: String!`	path to the internal input file. Should not be null. This is an absolute file path on the device, and it's the infrastructure/client's responsibility to make sure the file path is readable.

Throws
`java.io.IOException`

fun openInternalOutputFile(pathname: String!): OutputStream!

Provides an OutputStream to an internal file used by the testing infrastructure.

Parameters
`pathname: String!`	path to the test file dependency. Should not be null. Can be either a relative or absolute path. If relative, the implementation will read the input file from the test apk's asset directory

Throws
`java.io.IOException`

fun openOutputFile(pathname: String!): OutputStream!

Provides an OutputStream to a test output file.

Parameters
`pathname: String!`	path to the test file dependency. Should not be null. Can be either a relative or absolute path. If relative, the implementation will make a best effort attempt to a writable output dir based on API level.

Throws
`java.io.IOException`

fun openOutputFile(pathname: String!, append: Boolean): OutputStream!

Provides an OutputStream to a test output file.

Parameters
`pathname: String!`	path to the test output file. Should not be null.
`append: Boolean`	if true, then the lines will be added to the end of the file rather than overwriting.

Returns
`OutputStream!`	an OutputStream to the given output file.

Throws
`java.io.IOException`
