test.data.table {data.table} R Documentation

## Runs a set of tests.

### Description

Runs a set of tests to check data.table is working correctly.

### Usage

test.data.table(script = "tests.Rraw", verbose = FALSE, pkg = ".",
silent = FALSE,
showProgress = interactive() && !silent)


### Arguments

 script Run arbitrary R test script. verbose TRUE sets options(datatable.verbose=TRUE) for the duration of the tests. This tests there are no errors in the branches that produce the verbose output, and produces a lot of output. The output is normally used for tracing bugs or performance tuning. Tests which specifically test the verbose output is correct (typically looking for an expected substring) always run regardless of this option. pkg Root directory name under which all package content (ex: DESCRIPTION, src/, R/, inst/ etc..) resides. Used only in dev-mode. silent Controls what happens if a test fails. Like silent in try, TRUE causes the error message to be suppressed and FALSE to be returned, otherwise the error is returned. showProgress Output 'Running test ...\r' at the start of each test?

### Details

Runs a series of tests. These can be used to see features and examples of usage, too. Running test.data.table will tell you the full location of the test file(s) to open.

Setting silent=TRUE sets showProgress=FALSE too, via the default of showProgress.

### Value

If all tests were successful, TRUE is returned. Otherwise, see the silent argument above. silent=TRUE is intended for use at the start of production scripts; e.g. stopifnot(test.data.table(silent=TRUE)) to check data.table is passing its own tests before proceeding.
