Test::DatabaseRow::Object(3) examine database rows

SYNOPSIS


use Test::More tests => 1;
use Test::DatabaseRow::Object;

# setup the test
my $tdr = Test::DatabaseRow::Object->new(
sql_and_bind => "SELECT * FROM contacts WHERE cid = '123'",
tests => [ name => "trelane" ],
);
# do the test and get a result back
my $result_object = $tdr->tests_ok();
# have those results render to Test::Builder
$result_object->pass_to_test_builder("my database test");

DESCRIPTION

This module provides the underlying functionality of "Test::DatabaseRow".

Accessors

These are the read only accessors of the object. They may be (optionally) set at object creation time by passing their name and value to the constructor.

Each accessor may be queried by prefixing its name with the "has_" to determine if it has been set or not.

db_results
An arrayref of hashrefs, each representing a row returned from the database. Each key in the hashref should be the column name and the value the corresponding field's value. This datastructure is identical to that.

If this accessor is not passed then it will be populated on first use by executing the contents of "sql_and_bind" against the passed "dbh".

db_results_dumped
A string representation of the database results.

If this accessor is not passed then it will be populated on first use by using Test::Builder's explain function on "db_results"

sql_and_bind
The SQL and bind variables to execute if no results were passed into the db_results hash. This should be an arrayref containing the SQL as the first element and the bind values as further values.

This accessor will automatically coerce a simple scalar passed in into a single

If this accessor is not passed then it will be populated on first use by building SQL from the "where" and "table" accessors.

dbh
The database handle used to execute the SQL statement in "sql_and_bind" if no "db_results" were passed.
table
The table name used to build the SQL query if no value is passed to "sql_and_bind". String.
where
The data structure used to build the where clause of the SQL query if no value is passed to <sql_and_bind>.

This accessor value should be a hashref of hashrefs, with the outer keys being the SQL comparison operator, the inner keys being the field names and the inner values being the values to match against. For example:

  { 
    '='    => { first => "Fred", last => "Flintstone", },
    'like' => { address => "%Bedrock%" },
  }

Values of "undef" will automatically converted into checks for NULLs.

This accessor automatically coerces array refs that are passed into a pure equals hashref. For example:

  [ foo => "bar", bazz => "buzz" ]

Will be coerced into:

  { "=" => { foo => "bar", bazz => "buzz" } }

See ``where'' in Test::DatabaseRow for a more detailed explanation.

verbose
Truth value, default false. Controls if the diagnostic messages printed during "row_ok" on failure contain details of the SQL executed or not.
verbose_data
Truth value, default false. Controls if the diagnostic messages printed during "row_ok" on failure contain a Data::Dumper style dump of the resulting rows from the database.
force_utf8
Truth value, default false. Controls if the utf8 flag should be turned on on values returned from the database. See ``utf8 hacks'' in Test::DatabaseRow for why this might be important.

This flag only effects data that this module places into "db_resutls". If you manually populate this accessor this flag will have no effect.

tests
If set, enables specified tests on the first element of "db_results" when "row_ok" is called.

This accessor value should be a hashref of hashrefs, with the outer keys being the Perl comparison operator, the inner keys being the field names and the inner values being the values to test against. For example:

  { 
    'eq' => { first => "Fred", last => "Flintstone", },
    '=~' => { address => "%Bedrock%" },
  }

This accessor automatically coerces array refs that are passed into a hashref structure, converting things that look like strings into "eq" tests, things that look like numbers into "==" tests and things that are references to regular expressions into "=~" tests. Foe example:

  [ num => 123, letters => "abc", kinda => qr/substring/ ]

Will be coerced into

  {
    '==' => { num => 123, },
    'eq' => { letters => "abc", },
    '=~' => { kinda => qr/substring/ },
  }

See ``tests'' in Test::DatabaseRow for a more detailed explanation.

check_all_rows
Boolean to determine if we should test all rows (during "db_results_ok" and "test_ok") or just check the first row. Default true.
results
If set, enable tests to check the number of rows we returned by "db_results" is exactly this value when "row_ok" is called. Integer.
max_results
If set, enable tests to check the number of rows we returned by "db_results" is at most this value when "row_ok" is called. Integer.
min_results
If set, enable tests to check the number of rows we returned by "db_results" is at least this value when "row_ok" is called. Integer.

Methods

new(...)
Simple constructor. Passing arguments to the constructor sets the values of the accessors.
number_of_results_ok
Returns a Test::DatabaseRow::Result that represents if the number of results in "db_results" match the requirements for the number of results.
row_at_index_ok( $row_index )
Returns a Test::DatabaseRow::Result that represents if the element corresponding to the passed row index in "db_results" match the tests defined in "tests".
db_results_ok
Returns a Test::DatabaseRow::Result that represents if all elements in "db_results" match the tests defined in "tests".
test_ok
Returns a Test::DatabaseRow::Result that represents if the number of results in "db_results" match the requirements for the number of results and all elements in "db_results" match the tests defined in "tests".
