.PP
This method removes the test SQLite database in t/var/BCS.db
and then creates a new, empty database.
.PP
This method will call \fBdeploy_schema()\fR by default, unless the
deploy flag is set to 0.
.PP
This method will call \fBpopulate_schema()\fR if the populate argument
is set to a true value.
.SS "has_custom_dsn"
.IX Subsection "has_custom_dsn"
Returns true if the \s-1BCS_TEST_DSN\s0 environment variable is set.
.SS "deploy_schema"
.IX Subsection "deploy_schema"
.Vb 1
\&  Bio::Chado::Schema::Test\->deploy_schema( $schema );
.Ve
.PP
This method does one of two things to the schema.  It can either call
the experimental \f(CW$schema\fR\->\fBdeploy()\fR if the \s-1BCSTEST_SQLT_DEPLOY\s0 environment
variable is set, otherwise the default is to read in the t/lib/sqlite.sql
file and execute the \s-1SQL\s0 within. Either way you end up with a fresh set
of tables for testing.
.SS "populate_schema"
.IX Subsection "populate_schema"
.Vb 1
\&  Bio::Chado::Schema::Test\->populate_schema( $schema );
.Ve
.PP
After you deploy your schema you can use this method to populate
the tables with test data.
