Some methods angular material, i need to unit test of each one, but i don't know how

/**
 * Setup the filter for a table
 * @param dataTable data source to setup
 */
private setupFilter(dataTable: MatTableDataSource<Element>) {
    dataTable.filterPredicate = (data: any, filter: string) => {
        filter = filter.toLowerCase();
        return data.name.toLowerCase().includes(filter)
            || data.description.toString().includes(filter);
    };
}

    if (column === 'name') {
        this.errorInName.required = value === '';
        this.errorInName.maxlength = value.length > Constants.MAX_LENGTH_NAME;
        return;
