all_passed: Did all of the validations fully _pass_?

In pointblank: Data Validation and Organization of Metadata for Local and Remote Tables

Did all of the validations fully pass?

Description

Given an agent's validation plan that had undergone interrogation via interrogate(), did every single validation step result in zero failing test units? Using the all_passed() function will let us know whether that's TRUE or not.

Usage

all_passed(agent, i = NULL)

Arguments

agent	The pointblank agent object ⁠obj:<ptblank_agent>⁠ // required A pointblank agent object that is commonly created through the use of the create_agent() function.
i	Validation step numbers ⁠vector<integer>⁠ // default: NULL (optional) A vector of validation step numbers. These values are assigned to each validation step by pointblank in the order of definition. If NULL (the default), all validation steps will be used for the evaluation of complete passing.

Details

The all_passed() function provides a single logical value based on an interrogation performed in the agent-based workflow. For very large-scale validation (where data quality is a known issue, and is perhaps something to be tamed over time) this function is likely to be less useful since it is quite stringent (all test units must pass across all validation steps).

Should there be a requirement for logical values produced from validation, a more flexible alternative is in using the test (⁠test_*()⁠) variants of the validation functions. Each of those produce a single logical value and each and have a threshold option for failure levels. Another option is to utilize post-interrogation objects within the agent's x-list (obtained by using the get_agent_x_list() function). This allows for many possibilities in producing a single logical value from an interrogation.

Value

A logical value.

Examples

Create a simple table with a column of numerical values.

tbl <- dplyr::tibble(a = c(4, 5, 7, 8))

tbl
#> # A tibble: 4 x 1
#>       a
#>   <dbl>
#> 1     4
#> 2     5
#> 3     7
#> 4     8

Validate that values in column a are always greater than 4.

agent <-
  create_agent(tbl = tbl) %>%
  col_vals_gt(columns = a, value = 3) %>%
  col_vals_lte(columns = a, value = 10) %>%
  col_vals_increasing(columns = a) %>%
  interrogate()

Determine if these column validations have all passed by using all_passed() (they do).

all_passed(agent = agent)

#> [1] TRUE
